The role of executive functions in the control of aggressive behavior

An extensive literature suggests a link between executive functions and aggressive behavior in humans, pointing mostly to an inverse relationship, i.e., increased tendencies toward aggression in individuals scoring low on executive function tests. This literature is limited, though, in terms of the groups studied and the measures of executive functions. In this paper, we present data from two studies addressing these issues. In a first behavioral study, we asked whether high trait aggressiveness is related to reduced executive functions. A sample of over 600 students performed in an extensive behavioral test battery including paradigms addressing executive functions such as the Eriksen Flanker task, Stroop task, n-back task, and Tower of London (TOL). High trait aggressive participants were found to have a significantly reduced latency score in the TOL, indicating more impulsive behavior compared to low trait aggressive participants. No other differences were detected. In an EEG-study, we assessed neural and behavioral correlates of error monitoring and response inhibition in participants who were characterized based on their laboratory-induced aggressive behavior in a competitive reaction time task. Participants who retaliated more in the aggression paradigm and had reduced frontal activity when being provoked did not, however, show any reduction in behavioral or neural correlates of executive control compared to the less aggressive participants. Our results question a strong relationship between aggression and executive functions at least for healthy, high-functioning people.

Hammaslääkärin ura. Odotukset ja kokemukset. [Career Expectations and Experiences of Dentists]

Tutkimuksella selvitettiin eri tekijöiden merkitystä hammaslääkärien tehdessä uraansa koskevia valintoja lähtien ammatinvalinnasta. Tutkimuksessa verrattiin erilaisissa työpaikoissa toimivien hammaslääkärien sekä hammaslääketieteen opiskelijoiden odotuksia ja kokemuksia. Tutkimus tehtiin kyselynä postitse lähetetyin lomakkein. Kyselyyn osallistui 350 hammaslääkäriä ja 115 opiskelijaa. Kiinnostus lääketieteeseen ja työn konkreettisuus olivat keskeisimmät syyt lähteä hammaslääketiedettä opiskelemaan. Suurin osa sekä hammaslääkäreistä että opiskelijoista valitsisi vähintään todennäköisesti saman ammatin uudelleen, hammaslääkäreistä yksityishammaslääkärit useimmin. 69 % hammaslääkäreistä oli aloittanut työuransa terveyskeskuksessa, opiskelijoista 46 % toivoi työpaikkaa yksityissektorilta ja 37 % terveyskeskuksesta. Hammaslääkärit kokivat työn mielekkyyden, positiivisen kaiun, työn ja elämän reunaehtojen sekä taloudellisen turvallisuuden vaikuttaneen ensimmäiseen työpaikkaan menoon vähemmän kuin opiskelijat arvioivat niiden vaikuttavan. Työssä tärkeänä sekä hammaslääkärit että opiskelijat pitivät hyviä työolosuhteita ja mielekästä työn sisältöä. Toimiva yhteistyö työparin kanssa oli myös erittäin tärkeää. Hammaslääkärit pitivät hyviä työoloja ja autonomiaa tärkeämpinä kuin opiskelijat, joille puolestaan uralla eteneminen ja työajan joustot olivat tärkeämpiä. Hammaslääkärit arvostivat työtä ja työssä suoriutumista sekä hyvää työpaikkaa enemmän kuin opiskelijat. Parhaiten työssään toteutuvana suhteessa asian merkitykseen hammaslääkärit kokivat autonomian ja huonoiten ilmapiirin. Naiset kokivat asioiden toteutumisessa enemmän puutteita kuin miehet. Työpaikkaansa heikosti sitoutuneita oli 8 %, joista valtaosa terveyskeskushammaslääkäreitä. Heikosti sitoutuneet kokivat sitoutuneita huonompina varsinkin työilmapiirin, työolosuhteet ja mahdollisuuden uralla etenemiseen. Hammaslääkärit olivat halukkaampia jatkokoulutukseen kuin kokivat siihen olevanmahdollisuuksia; 25 % oli harkinnut erikoistumista, mutta luopunut ajatuksesta, ja20 % halusi erikoistua, mutta koki siihen käytännön esteitä. Jatkossa tulisi tarkemmin analysoida ja toistettavin tutkimuksin seurata hammaslääkärien urakokemuksia ja valintoja sekä koetun työssä vallitsevan tilanteen ja asioiden merkityksen välistä suhdetta. Myös opiskelijoiden urasuunnitelmia ja arvostuksia tulisi tutkia säännöllisin väliajoin.

The effects of social networks on work-team effectiveness

This is a study of team social networks, their antecedents and outcomes. In focusing attention on the structural configuration of the team this research contributes to a new wave of thinking concerning group social capital. The research site was a random sample of Finnish work organisations. The data consisted of 499 employees in 76 teams representing 48 different organisations. A systematic literature review and quantitative methods were used in conducting the research: the former primarily to establish the current theoretical position on the relationships among the variables and the latter to test these relationships. Social network analysis was the primary method used in identifying the social-network relations among the work-team members. The first and key contribution of this study is that it relates the structuralnetwork properties of work teams to behavioural outcomes, attitudinal outcomes and, ultimately, team performance. Moreover, it shows that addressing attitudinal outcomes is also important in terms of team performance; attitudinal outcomes (team identity) mediated the relationship between the team’s performance and its social network. The second contribution is that it examines the possible antecedents of the social structure. It is thus one response to Salancik’s (1995) call for a network theory in that it explains why certain network characteristics exist. Itdemonstrates that irrespective of whether or not a team is heterogeneous in terms of age or gender, educational diversity may protect it from centralisation. However, heterogeneity in terms of gender turned out to have a negative impact on density. Thirdly, given the observation that the benefits of (team) networks are typically theorised and modelled without reference to the nature of the relationships comprising the structure, the study directly tested whether team knowledge mediated the effects of instrumental and expressive network relationships on team performance. Furthermore, with its focus on expressive networks that link the workplace to a more informal world, which have been rather neglected in previous research, it enhances knowledge of teams andnetworks. The results indicate that knowledge sharing fully mediates the influence of complementarities between dense and fragmented instrumental network relationships, thus providing empirical validation of the implicit understanding that networks transfer knowledge. Fourthly, the study findings suggest that an optimal configuration of the work-team social-network structure combines both bridging and bonding social relationships.

General terms and rigidity: another solution to the trivialization problem

In this paper I am concerned with the problem of applying the notion of rigidity to general terms. In Naming and Necessity, Kripke has clearly suggested that we should include some general terms among the rigid ones, namely, those common nouns semantically correlated with natural substances, species and phenomena, in general, natural kinds -'water', 'tiger', 'heat'- and some adjectives -'red', 'hot', 'loud'. However, the notion of rigidity has been defined for singular terms; after all, the notion that Kripke has provided us with is the notion of a rigid designator. But general terms do not designate single individuals: rather, they apply to many of them. In sum, the original concept of rigidity cannot be straightforwardly applied to general terms: it has to be somehow redefined in order to make it cover them. As is known, two main positions have been put forward to accomplish that task: the identity of designation conception, according to which a rigid general term is one that designates the same property or kind in all possible worlds, and the essentialist conception, which conceives of a rigid general term as an essentialist one, namely, a term that expresses an essential property of an object. My purpose in the present paper is to defend a particular version of the identity of designation conception: on the proposed approach, a rigid general term will be one that expresses the same property in all possible worlds and names the property it expresses. In my opinion, the position can be established on the basis of an inference to the best explanation of our intuitive interpretation and evaluation, relative to counterfactual circumstances, of statements containing different kinds of general terms, which is strictly analogous to our intuitive interpretation and evaluation, relative to such circumstances, of statements containing different kinds of singular ones. I will argue that it is possible to offer a new solution to the trivialization problem that is thought to threaten all versions of the identity of designation conception of rigidity. Finally, I will also sketch a solution to the so-called 'over-generalization and under-generalization problems', both closely related to the above-mentioned one.

Implementation of a trauma registry in a brazilian public hospital: the first 1,000 patients

OBJECTIVE: Show the steps of a Trauma Registry (TR) implementation in a Brazilian public hospital and evaluate the initial data from the database.METHODS: Descriptive study of the a TR implementation in João XXIII Hospital (Hospital Foundation of the state of Minas Gerais) and analysis of the initial results of the first 1,000 patients.RESULTS: The project was initiated in 2011 and from January 2013 we began collecting data for the TR. In January 2014 the registration of the first 1000 patients was completed. The greatest difficulties in the TR implementation were obtaining funds to finance the project and the lack of information within the medical records. The variables with the lowest completion percentage on the physiological conditions were: pulse, blood pressure, respiratory rate and Glasgow coma scale. Consequently, the Revised Trauma Score (RTS) could be calculated in only 31% of cases and the TRISS methodology applied to 30.3% of patients. The main epidemiological characteristics showed a predominance of young male victims (84.7%) and the importance of aggression as a cause of injuries in our environment (47.5%), surpassing traffic accidents. The average length of stay was 6 days, and mortality 13.7%.CONCLUSION: Trauma registries are invaluable tools in improving the care of trauma victims. It is necessary to improve the quality of data recorded in medical records. The involvement of public authorities is critical for the successful implementation and maintenance of trauma registries in Brazilian hospitals.

Creating generation Y sources of motivation for enhanced performance

New challenges have been created in the modern work environment as the diversity of the workforce is greater than ever in terms of generations. There will become a large demand of generation Y employees as the baby boomer generation employees retire at an accelerated rate. The purpose of this study is to investigate Y generation specific characteristics and to identify motivational systems to enhance performance. The research questions are: 1. What are Y generation characteristics? 2. What motivational systems organizations can form to motivate Y generation employees and in turn, create better performance? The Y generation specific characteristics identified from the literature include; achievement oriented; confident; educated; multitasking; having a need for feedback; needing management support; sociable and tech savvy. The proposed motivational systems can be found in four areas of the organization; HRM, training and development, communication and decision making policies. Three focus groups were held to investigate what would motivate generation Y employees to achieve better performance. Two of these focus groups were Finnish natives and the third consisted of international students. The HRM systems included flexibility and a culture of fun. It was concluded that flexibility within the workplace and role was a great source of motivation. Culture of fun was not responded to as favorably although most focus group participants rated enjoyableness as one of their top motivating factors. Training and development systems include training programs and mentoring as sources of potential motivation. Training programs were viewed as a mode to gain a better position and were not necessarily seen as motivational systems. Mentoring programs were not concluded to have a significant effect on motivation. Communication systems included keeping up with technology, clarity and goals as well as feedback. Keeping up with technology was seen as an ineffective tool to motivate. Clarity and goal setting was seen as very important to be able to perform but not necessarily motivating. Feedback had a highly motivating effect on these focus groups. Decision making policies included collaboration and teamwork as well as ownership. Teams were familiar and meet the social needs of Y generation employees and are motivating. Ownership was equated with trust and responsibility and was highly valued as well as motivating to these focus group participants.

The adjustment from Russia to Finland for corporate repatriates: How the repatriation experience influences readjustment in the workplace

To manage foreign operations, companies must often send their employees on international assignments. Repatriating these expatriates can be difficult because they have been forgotten during their posting, and their new experiences are not utilised. In addition to the possible difficulties in organisational repatriation, the returnee can suffer from readjustment problems after a lengthy stay abroad has changed their habits and even identity. This thesis examines the repatriation experience of Finnish assignees returning from Russia. The purpose of the study is to understand how the repatriation experience influences their readjustment to work in Finland. This experience is influenced by many factors including personal and situational changes, the repatriation process, job and organisational factors, and individual’s motives. The theoretical background of the study is founded on two models of repatriation adjustment. A refined, holistic theoretical framework for the study is created. It describes the formation of the repatriation experience and its importance for readjustment to work and retention. The qualitative research approach is suitable for the thesis which examines the returnees’ personal experiences and feelings: a qualitative case study aims to explain the phenomenon in-depth and comprehensively. The data was collected in summer 2013 through semi-standardised interviews with eight Finnish repatriates. They had returned from Russia within the last two years. The data was analysed by structuring the interview transcripts using template analysis. The results supported earlier literature and suggest that the re-entry remains a challenging phase for both the individual and the company. For some, adjusting to a new job was difficult for various reasons. The repatriates underwent personal change and development and felt it was for the better. Many repatriates criticised the company’s repatriation process upon return. Finding a suitable return job was not clear. Instead, the returnees had to be active in finding a new position. Many assignees had only modest career-related motives regarding the assignment and they had realistic expectations about the return. Therefore they were not extremely surprised or dissatisfied when they were not actively offered positions or support by the company. The significance of motives stood out even more than the theory predicted. As predicted, they are linked to the expectations of employees. Moreover, if the employees are motivated to remain in the company, they can tolerate partly a negative repatriation experience. Despite the complexity of the return and readjustment, the assignment as a whole was seen as a rewarding experience by all participants.

The many faces of strikes : attitudes towards industrial action by labour, management and human resources

Strikes provide a current, fresh but also a seldom-addressed issue to study from economic sciences perspective. This study provides to filling this research gap by trying to identify attitudes towards strikes that can be found inside organizations. The research problem this study then sets out to answer is: “What kinds of attitudes exist inside organizations towards industrial actions and how attitudes vary between labour, management and human resources?” This study has been planned with a view to test how qualitative attitudinal research, as a method, is suited to studying a phenomenon such as strike. At the heart of this research approach lies an assumption linked to rhetoric social psychology, that attitude is a phenomenon that can be identified in argumentation. For this research 10 semi-structured interviews in 4 organizations were conducted utilizing statements and pictures as stimulants for discussion. The material was transcribed and analysed following the two levels, categorical and interpretive, demanded by the chosen method. Altogether five attitudes were discovered; three of them negative, one indifferent and one positive by nature. The negative attitudes of unfairness, failure and personification towards strikes represented the side of strikes that was perhaps the most anticipated, portraying the contradictions between employees and employer. The attitude of ordinariness, which portrayed indifference, and the positive attitude of change however, were more unanticipated findings. They reflect shared understanding and trust between conflict parties. The utilization of qualitative attitudinal approach to study strikes was deemed successful. The results of this study support prior literature on workplace conflicts for example in regards of the definition of conflict and typologies conflicts. In addition the multifaceted nature of strikes can be perceived as one statement supported by this study. It arises in the nature of the attitudes, the diversity of discussion themes during the interviews as well as in the extent of possible theories to apply.

Frequency of B cells in normal mice which recognize self proteins

The mechanism whereby the immune system avoids self-aggression is one of the central issues of Immunology. The discovery of natural autoantibodies, mainly of IgM isotype, and of idiotypic interactions between antibodies indicates that elements of the immune system interact with self constituents and with themselves. Results of studies with soluble antibodies have indicated that the pool of circulating IgM represents the end result of a highly selective process of B cells activation and differentiation by self proteins resulting in the formation of a network. The objective of the present work was to determine the frequency of self-reacting B cells in normal mice. We were able to detect B cells that recognize self proteins present in extracts of different organs in normal adult, 2-3-month old, BALB/c and C57BL/6 mice with an ELISA spot assay. About 1% of total IgM-secreting cells among small, LPS-stimulated spleen cells reacted with organ extracts, whereas among large spleen cells the frequency was 5- to 10-fold lower. Immunization induced an increase in the frequency of IgM-secreting cells. The present results provide cellular evidence for the results of studies done at the serological level. The physiological role of these self-recognizing cells, as well as their participation in autoimmune processes, remain to be established

Eye color as an indicator of social rank in the fish Nile tilapia

We investigated the association of eye color with the dominant-subordinate relationship in the fish Nile tilapia, Oreochromis niloticus. Eye color pattern was also examined in relation to the intensity of attacks. We paired 20 size-matched fish (intruder: 73.69 ± 11.49 g; resident: 75.42 ± 8.83 g) and evaluated eye color and fights. These fish were isolated in individual aquaria for 10 days and then their eye color was measured 5 min before pairing (basal values). Twenty minutes after pairing, eye color and fights were quantified for 10 min. Clear establishment of social hierarchy was observed in 7 of 10 pairs of fish. Number of attacks ranged from 1 to 168 among pairs. The quartile was calculated for these data and the pairs were then divided into two classes: low-attack (1 to 111 attacks - 2 lower quartiles) or high-attack (112 to 168 attacks - 2 higher quartiles). Dominance decreased the eye-darkening patterns of the fish after pairing, while subordinance increased darkening compared to dominance. Subordinate fish in low-attack confrontations presented a darker eye compared to dominant fish and to the basal condition. We also observed a paler eye pattern in dominants that shared low-attack interactions after pairing compared to the subordinates and within the group. However, we found no differences in the darkening pattern between dominants and subordinates from the high-attack groups. We conclude that eye color is associated with social rank in this species. Moreover, the association between eye color and social rank in the low-attack pairs may function to reduce aggression.

Stress responses of the fish Nile tilapia subjected to electroshock and social stressors

Plasma cortisol and glucose levels were measured in 36 adult Nile tilapia males, Oreochromis niloticus (standard length, mean ± SD, 14.38 ± 1.31 cm), subjected to electroshock and social stressors. Pre-stressor levels were determined 5 days after the adjustment of the fish to the experimental aquaria (1 fish/aquarium). Five days later, the effects of stressors on both cortisol and glucose levels were assessed. The following stressors were imposed for 60 min: pairing with a larger resident animal (social stressor), or a gentle electroshock (AC, 20 V, 15 mA, 100 Hz for 1 min every 4 min). Each stressor was tested in two independent groups, one in which stress was quantified immediately after the end of the 60-min stressor imposition (T60) and the other in which stress was quantified 30 min later (T90). Pre-stressor values for cortisol and glucose were not statistically different between groups. Plasma cortisol levels increased significantly and were of similar magnitude for both electroshock and the social stressor (mean ± SD for basal and final samples were: electroshock T60 = 65.47 ± 15.3, 177.0 ± 30.3; T90 = 54.8 ± 16.0, 196.2 ± 57.8; social stress T60 = 47.1 ± 9.0, 187.6 ± 61.7; T90 = 41.6 ± 8.1, 112.3 ± 26.8, respectively). Plasma glucose levels increased significantly for electroshock at both time points (T60 and T90), but only at T90 for the social stressor. Initial and final mean (± SD) values are: electroshock T60 = 52.5 ± 9.2, 115.0 ± 15.7; T90 = 35.5 ± 1.1, 146.3 ± 13.3; social stress T60 = 54.8 ± 8.8, 84.4 ± 15.0; T90 = 34.5 ± 5.6, 116.3 ± 13.6, respectively. Therefore, electroshock induced an increase in glucose more rapidly than did the social stressor. Furthermore, a significant positive correlation between cortisol and glucose was detected only at T90 for the social stressor. These results indicate that a fish species responds differently to different stressors, thus suggesting specificity of fish stress response to a stressor.

The polymorphism of the serotonin-2A receptor T102C is associated with age

Epidemiological investigations suggest that T102C polymorphism of gene 5-HT2A may be associated with mean life span because diseases and behaviors related to this polymorphism, such as schizophrenia, suicide, aggression, and addiction, may potentially shorten mean life span. A sample of 687 individuals without previous neuropsychiatric disease was genotyped and separated into 3 groups according to their gender and age: 14-45 years old, 46-64 years old and 65-100 years old. Molecular genotyping was performed using the technique of polymerase chain reaction followed by restriction fragment length polymorphism using HpaII restriction enzyme. 5-HT2A genotype frequencies were: TT = 21.5% (148), CC = 16.6% (114) and TC = 61.9% (425) and allele frequencies were T = 52.5% and C = 46.5%. Significant differences were found between mean age of the TT genotype carriers (60.27 ± 12.60 years) and TC genotype carriers (56.80 ± 13.18 years) of T102C polymorphism of gene 5-HT2A (P = 0.026) as well as the age groups (P = 0.012). Carriers of genotype TT were older than the other two genotypes, whereas carriers of genotype CC had an intermediate age compared with TT and CC subjects. The present results demonstrate an association between T102C polymorphism of gene 5-HT2A and age. Our results suggest that T102C polymorphism of gene 5-HT2A is associated with mean life span, and thus this gene becomes a possible candidate for the group of adaptive genes to meat consumption proposed in the literature. Further studies should be conducted in order to elucidate this association.

Long-term social recognition memory in adult male rats: factor analysis of the social and non-social behaviors

A modified version of the intruder-resident paradigm was used to investigate if social recognition memory lasts at least 24 h. One hundred and forty-six adult male Wistar rats were used. Independent groups of rats were exposed to an intruder for 0.083, 0.5, 2, 24, or 168 h and tested 24 h after the first encounter with the familiar or a different conspecific. Factor analysis was employed to identify associations between behaviors and treatments. Resident rats exhibited a 24-h social recognition memory, as indicated by a 3- to 5-fold decrease in social behaviors in the second encounter with the same conspecific compared to those observed for a different conspecific, when the duration of the first encounter was 2 h or longer. It was possible to distinguish between two different categories of social behaviors and their expression depended on the duration of the first encounter. Sniffing the anogenital area (49.9% of the social behaviors), sniffing the body (17.9%), sniffing the head (3%), and following the conspecific (3.1%), exhibited mostly by resident rats, characterized social investigation and revealed long-term social recognition memory. However, dominance (23.8%) and mild aggression (2.3%), exhibited by both resident and intruders, characterized social agonistic behaviors and were not affected by memory. Differently, sniffing the environment (76.8% of the non-social behaviors) and rearing (14.3%), both exhibited mostly by adult intruder rats, characterized non-social behaviors. Together, these results show that social recognition memory in rats may last at least 24 h after a 2-h or longer exposure to the conspecific.

Sopeutumattomien oppilaiden tunne- ja itsesäätelytaitojen kehittyminen: Oppilaiden ja opettajien arvioita ja kokemuksia Aggression portaat -interventiosta

Tässä tutkimuksessa tarkastellaan sopeutumattomien erityisoppilaiden tunne- ja itsesäätelytaitojen kehittymistä Aggression portaat -interventio-ohjelman avulla kolmen vuoden tutkimusjakson aikana. Käsite sopeutumaton oppilas ei ole yksiselitteisesti määriteltävissä, mutta tässä tutkimuksessa sillä tarkoitetaan yleisopetussuunnitelman mukaan opiskelevaa oppilasta, joka käyttäytymiseen ja tunne-elämään liittyvien haasteidensa vuoksi on saanut siirron erityisopetuksen oppilaaksi ja saa enintään 10 oppilaan opetusryhmässä erityistä pedagogista tukea. Tutkimuksen yksi keskeinen tehtävä oli tutkia, onko tunne- ja itsesäätelytaitojen opettamisesta hyötyä sopeutumattomien oppilaiden tunteiden hallinnan ja käyttäytymisen itsesäätelyn kannalta. Tutkimuksen teoreettisena viitekehyksenä on Rose-Krasnorin (1997) malli yksilön sosioemotionaalisesta kompetenssista täydennettynä muiden tutkijoiden näkemyksillä. Sosioemotionaalinen kompetenssi on yläkäsite, johon kuuluvat alakäsitteinä tunne- ja itsesäätelytaidot, sosiokognitiiviset taidot ja sosiaaliset taidot. Lisäksi sosioemotionaaliseen kompetenssiin vaikuttavat kiintymyssuhteet ja osallisuus sekä tavoitteet vuorovaikutuksessa ja konteksti. Tässä tutkimuksessa keskitytään tunne- ja itsesäätelytaitoihin. Interventioryhmän (N=36) muodostivat Varsinais-Suomen alueella opiskelevat sopeutumattomien oppilaiden erityiskoulun 8-13-vuotiaat oppilaat, joille opetettiin tunne- ja itsesäätelytaitoja Aggression portaat -opetusmateriaaliin (Cacciatore 2007) pohjautuvan intervention avulla. Kontrolliryhmän (N=26) oppilaat olivat interventioryhmän oppilaiden ikäisiä ja he opiskelivat Varsinais-Suomen alueen kouluissa pienluokissa myös käyttäytymiseen ja tunne-elämään liittyvien haasteidensa vuoksi. Kontrolliryhmän oppilaat eivät saaneet tutkimusjakson aikana interventio-ohjelman mukaista opetusta. Interventioryhmän oppilaat kävivät erityiskoulua, jossa kaikilla oppilailla oli sopeutumisongelmia ja kontrolliryhmän oppilaat opiskelivat yleisopetuksen koulujen yhteydessä olevilla sopeutumattomien oppilaiden pienluokilla. Tutkimusaineisto on kerätty vuosina 2010-2012. Tutkimusmetodeina olivat sekä oppilaille että opettajille laaditut Webropol-alustaiset kyselyt ja oppilaiden kirjoittamat väkivalta-aiheiset tekstit. Tutkimus- ja kontrolliryhmän oppilaille pidettiin ”Tunteiden hallinta ja käyttäytyminen”- kyselyn avulla alkumittaus syksyllä 2009 ja mittaus toistettiin keväällä 2010, 2011 ja 2012. Kyselyiden avulla selvitettiin, miten oppilaiden tunteiden kokeminen ja ilmaiseminen sekä tunteiden hallinta ja käyttäytymisen itsesäätely muuttuivat tutkimusjakson aikana. Kyselyssä kartoitettiin myös oppilaiden kokemuksia kiusaamisena ilmenevästä väkivallasta. Aineistolähtöisen sisällönanalyysin avulla selvitettiin oppilaiden kirjoitelmista heidän ajatuksiaan ja näkemyksiään väkivallasta ja ehdotuksia keinoista väkivallan vähentämiseksi. Keväällä 2012 interventioryhmän oppilaille ja opettajille laadittujen erillisten kyselyiden avulla selvitettiin sekä oppilaiden että opettajien arvioita ja kokemuksia oppilaiden tunne- ja itsesäätelytaitojen muutoksesta interventio-ohjelman avulla. Lisäksi oppilaat ja opettajat arvioivat pidettyjen tunnetaitotuntien hyödyllisyyttä oppilaille. Interventioryhmän opettajat arvioivat myös Aggression portaat -interventiomateriaalin käyttökelpoisuutta. Vuoden 2014 Perusopetuksen opetussuunnitelman perusteissa esitetyt velvoitteet opettaa kouluissa oppilaille tunne- ja vuorovaikutustaitoja edellyttävät tietoa konkreettisista käytänteistä ja tutkimusperustaisista interventio-ohjelmista. Tämän tutkimuksen tulokset osoittavat, että interventioryhmän muodostaneet sopeutumattomat oppilaat hyötyivät Aggression portaat -interventiosta. Heidän tunne- ja itsesäätelytaidoissaan tapahtui myönteistä kehitystä etenkin myönteisten tunnekokemusten lisääntymisen ja toisiin kohdistuneen fyysisen väkivallan vähenemisen osalta. Myös suhtautuminen väkivaltapelien ikärajoihin oli merkittävästi myönteisempää kuin kontrolliryhmän oppilailla, joilla kielteinen asenne lisääntyi selvästi tutkimusjakson aikana. Lisäksi interventioryhmän oppilailla oli keinoja itsensä rentouttamiseksi, päinvastoin kuin kontrolliryhmän oppilailla, joilla keinottomuuden kokemus jopa lisääntyi. Interventioryhmän oppilaat suhtautuivat hyvin kielteisesti toisen yllyttämiseen väkivaltaiseen tekoon ja kirjoittivat enemmän ajatuksiaan väkivallasta tuoden esille runsaasti ehdotuksia keinoista väkivallan vähentämiseksi. Myös oppilaat ja opettajat kokivat interventio-ohjelman oppilaiden kehityksen kannalta hyödylliseksi ja opettajat myös interventiomateriaalin käyttökelpoiseksi.
