Parent emotional functioning, parent responsiveness, and child adjustment

Over the past two decades, interest in the psychological development of children has steadily increased (Beg, Casey, & Saunders, 2007), presumably because statistics describing childhood psychological illness are alarming. Certain parent interaction styles or behaviors are known to influence child adjustment. According to attachment theory, the reason for these findings is that interaction with a caregiver informs an individual’s construction of an internal working model (IWM) of the self in relation to others in the environment. The purpose of this study was to gain a greater understanding of the factors contributing to child adjustment by examining the influence of parents’ emotional functioning and parent responsiveness to children’s bids for interaction. This dissertation tested a multivariate model of attachment-related processes and outcomes with an ethnically diverse sample. Results partially supported the model, in that parent emotional intelligence predicted some aspects of child adjustment. Overall, the study adds to knowledge about how parent characteristics influence child adjustment and provides support for conceptualizing emotional intelligence as a concrete and observable manifestation of the nonconscious attachment IWM.

Food customs of rural and urban Inupiaq elders and their relationships to select nutrition parameters, food insecurity, health, and physical and mental functioning

The Inupiaq Tribe resides north of the Arctic Circle in northwestern Alaska. The people are characterized by their continued dependence on harvested fish, game and plants, known as a subsistence lifestyle (Lee 2000:35-45). Many are suggesting that they leave their historical home and move to urban communities, places believed to be more comfortable as they age. Tribal Elders disagree and have stated, "Elders need to be near the river where they were raised" (Branch 2005:1). The research questions focused on differences that location had on four groups of variables: nutrition parameters, community support, physical functioning and health. A total of 101 Inupiaq Elders ≥ 50 years were surveyed: 52 from two rural villages, and 49 in Anchorage. Location did not influence energy intake or intake of protein; levels of nutrition risk and food insecurity; all had similar rates between the two groups. Both rural and urban Elders reported few limitations of ADLs and IADLs. Self-reported general health scores (SF-12.v2 GH) were also similar by location. Differences were found with rural Elders reporting higher physical functioning summary scores (SF-12.v2 PCS), higher mental health scores (SF-12.v2 MH), higher vitality and less pain even though the rural mean ages were five years older than the urban Elders. Traditional food customs appear to support the overall health and well being of the rural Inupiaq Elders as demonstrated by higher intakes of Native foods, stronger food sharing networks and higher family activity scores than did urban Elders. The rural community appeared to foster continued physical activity. It has been said that when Elders are in the rural setting they are near "people they know" and it is a place "where they can get their Native food" (NRC 2005). These factors appear to be important as Inupiaq Elders age, as rural Inupiaq Elders fared as well or better than Inupiaq Elders in terms of diet, mental and physical health.

The effects of parental nurturance and involvement on peer relationships and psychosocial functioning of young adults

This study examined peer relationships and psychosocial functioning as a function of maternal and paternal involvement and nurturance along with the moderating effects of gender, family form, and ethnicity. Prior research has shown the influence of mother’s involvement on peer relationship quality but not of fathers. Further, previous studies did not examine moderation by family form, gender, or ethnicity. The sample consisted of 1359 students who identified their biological mother and father as the most influential parental figures in their lives. Their ages ranged from 18 to 26; Sixty-one percent of the sample was Hispanic, 13% non-Hispanic Black, 25% non-Hispanic White; 76% female and 70% from intact families. The analytical strategy included using bivariate correlations and structural equation modeling to examine these relationships. ^ All dimensions of maternal and paternal nurturing and involvement were positively related to positive characteristics of peer relationships, self-esteem and life satisfaction consistent with the multicultural findings of PARTheory (Rohner, Khalique, & Cournoyer, 2005). A structural model was developed that was able to adequately account for the relationship between parental influence, peer relationships, and psychosocial functioning. These effects of both maternal and paternal influence were strongly moderated by culture, family form, and gender. Finally, a differential effect was found among parental influence with fathers having a greater influence on friendship quality and importance than mothers, despite greater maternal involvement. ^ These findings have theoretical, clinical, and social implications as they call for a socially based theoretical perspective within which to study these relationships. Such a perspective would better inform clinicians when using impaired social functioning as indicative of axial diagnosis, and for the implementation of social policy to encourage paternal involvement. ^

Parent's emotional expressiveness and child, parent, and family functioning

This study investigated associations between parents' expressed emotion during a series of play tasks with their child, and psychological assessments of parent, child, and family functioning. Parent and child dyads included 41 families with a child between ages 4 and 12 who sought a developmental assessment at the Youth and Family Development Program laboratory at Florida International University. Videotaped dyadic play tasks were rated, using an Emotional Expressiveness Rating Scale (EERS) developed for this study, for parents' communication of criticism, hostility, emotional over-involvement, indifference, and warmth toward their child. Associations between parent expressed emotion and parent, child, and family functioning were assessed. Negative expressed emotion in parents, particularly criticism, was correlated with externalizing child problems, high parental stress, and family conflict; parent warmth was correlated with parents' feeling rewarded by their child, and with family cohesion. The implications for mental health research and practice with parents and children are discussed.

Plant diversity influencing structure and functioning of Caatinga vegetation

O estudo dos efeitos que a diversidade de espécies pode causar nos processos ecossistêmicos tem crescido vertiginosamente nas últimas duas décadas. Diversos trabalhos experimentais realizados no mundo todo têm demonstrado que uma maior diversidade de plantas contribui para o aumento da produtividade de ecossistemas terrestres. Além disso, esse efeito pode influenciar processos em diversos níveis tróficos, contribuindo assim para a estabilidade dos processos ecossistêmicos a longo prazo. Paralelamente com os estudos do efeito da diversidade, muita atenção tem sido dada para desvendar o papel das características funcionais das espécies no funcionamento dos ecossistemas. Isto porque as características funcionais das espécies têm se mostrado importantes "peças" no entendimento dos efeitos que espécies individuais podem exercer nos ecossistemas e suas respostas ao ambiente. Nesta tese de doutorado eu explorei algumas lacunas de conhecimento dentro dessa área em crescente desenvolvimento conhecida na literatura ecológica como "biodiversidade e funcionamento dos ecossistemas". No primeiro capítulo, eu busquei evidências para mecanismos que podem explicar a relação positiva entre diversidade e funcionamento com foco em cinco mecanismos relacionados às interações entre plantas, tendo como parâmetro de funcionamento a produtividade primária. No segundo capítulo, eu utilizei técnicas para a estimativa de padrões de diversidade em escalas biogeográficas e bases de dados de satélites com longa duração para desvendar se a biodiversidade em escalas macroecológicas promove a estabilidade da produtividade dos ambientes terrestres no semiárido brasileiro. Por fim, o objetivo do terceiro capítulo foi entender como a perda da cobertura vegetal originária do uso da terra por comunidades tradicionais no semiárido brasileiro influenciaria os processos de interações entre plantas e o papel das características funcionais das espécies nessas interações. Acredito que a contribuição individual de cada capítulo preenche lacunas de conhecimento importantes dessa área da Ecologia que ainda se encontra em expansão.

A Naturalistic Assessment of the Organization of Children’s Memories Predicts Cognitive Functioning and Reading Ability

To explore the relationship between memory and early school performance, we used graph theory to investigate memory reports from 76 children aged 6–8 years. The reports comprised autobiographical memories of events days to years past, and memories of novel images reported immediately after encoding. We also measured intelligence quotient (IQ) and theory of mind (ToM). Reading and Mathematics were assessed before classes began (December 2013), around the time of report collection (June 2014), and at the end of the academic year (December 2014). IQ and ToM correlated positively with word diversity and word-to-word connectivity, and negatively with word recurrence. Connectivity correlated positively with Reading in June 2014 as well as December 2014, even after adjusting for IQ and ToM. To our knowledge, this is the first study demonstrating a link between the structure of children’s memories and their cognitive or academic performance.

Attachment, psychological functioning, and resilience within the street involved youth populations: describing youth who access community agency support

Youth homelessness is defined within the literature as youth who have left their homes and are living independent of parental figures and/or caregivers, have no stable residence or source of income, and lack access to the supports needed to make the challenging transition into adulthood (Canadian Observatory on Homelessness, 2015). Previous research studying homeless (or street-involved) youth has primarily focused on risk factors hindering the development of this population, and has largely ignored resilience, coping, and help-seeking behaviours. The current study examined the attachment styles (both categorically and dimensionally), psychological functioning, resilience, and help-seeking behaviours in street-involved youth of St. John’s, Newfoundland. Face-to face interviews were completed over a four-month period with 63 youth (42 males, 21 females) aged 15-29 (Mage = 20.00), recruited from a local community organization providing outreach services to street-involved youth. Results revealed the disproportionate struggles of the street-involved youth population, and highlighted higher levels of attachment insecurity, psychological distress and lower resilience compared to normative peers. Findings also showed a significant difference in psychological functioning, overall resilience, and emotional reactivity based on individual attachment style. In an exploratory model of help-seeking, a positive relationship was found between overall resilience (defined as a sense of mastery and sense of relatedness) and frequency of community service access. However, contrary to predictions, no relationships were found between frequency of community service access and attachment, psychological functioning, or emotional reactivity. Implications of the present findings in development of interventions for street-involved youth are discussed, in addition to strengths and limitations of the present research, and suggested areas of future inquiry.

Self-efficacy in depression: Bridging the gap between competence and real-world functioning

Background: Depression is the largest contributing factor to years lost to disability, and symptom remission does not always result in functional improvement. Comprehensive analysis of functioning requires investigation both of the competence to perform behaviours, as well as actual performance in the real world. Further, two independent domains of functioning have been proposed: adaptive (behaviours conducive to daily living skills and independent functioning) and interpersonal (behaviours conducive to the successful initiation and maintenance of social relationships). To date, very little is known about the relationship between these constructs in depression, and the factors that may play a key role in the disparity between competence and real-world performance in adaptive and interpersonal functioning. Purpose: This study used a multidimensional (adaptive and interpersonal functioning), multi-level (competence and performance) approach to explore the potential discrepancy between competence and real-world performance in depression, specifically investigating whether self-efficacy (one’s beliefs of their capability to perform particular actions) predicts depressed individuals’ underperformance in the real world relative to their ability. A comparison sample of healthy participants was included to investigate the level of depressed individuals’ impairment, across variables, relative to healthy individuals. Method: Forty-two participants with depression and twenty healthy participants without history of, or current, psychiatric illness were recruited in the Kingston, Ontario community. Competence, self-efficacy, and real-world functioning all in both adaptive and interpersonal domains, and symptoms were assessed during a single-visit assessment. Results: Relative to healthy individuals, depressed individuals showed significantly poorer adaptive and interpersonal competence, adaptive and interpersonal functioning, and significantly lower self-efficacy for adaptive and interpersonal behaviours. Self-efficacy significantly predicted functional disability both in the domain of adaptive and interpersonal functioning. Interpersonal self-efficacy accounted for significant variance in the discrepancy between interpersonal competence and functioning. Conclusions: The current study provides the first data regarding relationships among competence, functioning, and self-efficacy in depression. Self-efficacy may play an important role in the deployment of functional skills in everyday life. This has implications for therapeutic interventions aimed at enhancing depressed individuals’ engagement in functional activities. There may be additional intrinsic or extrinsic factors that influence the relationships among competence and functioning in depression.

Psychosocial Functioning in Women with Symptoms of Persistent Genital Arousal

Persistent genital arousal disorder (PGAD) is characterized by physiological sexual arousal (vasocongestion, sensitivity of the genitals and nipples) that is described as distressing, and sometimes painful. Although awareness of PGAD is growing, there continues to be a lack of systematic research on this condition. The vast majority of published reports are case studies. Little is known about the symptom characteristics, biological factors, or psychosocial functioning associated with the experience of persistent genital arousal (PGA) symptoms. This study sought to characterize a sample of women with PGA (Study One); compare women with and without PGA symptoms on a series of biopsychosocial factors (Study Two); and undertake an exploratory comparison of women with PGA, painful PGA, and genital pain (Study Three)—all within a biopsychosocial framework. Symptom-free women, women with PGA symptoms, painful PGA, and genital pain, completed an online survey of biological factors (medical history, symptom profiles), psychological factors (depression, anxiety) and social factors (sexual function, relationship satisfaction). Study One found that women report diverse symptoms associated with PGA, with almost half reporting painful symptoms. In Study Two, women with symptoms of PGA reported significantly greater impairment in most domains of psychosocial functioning as compared to symptom-free women. In particular, catastrophizing of vulvar sensations was related to symptom ratings (i.e., greater severity, distress) and psychosocial outcomes (i.e., greater depression and anxiety). Finally, Study Three found that women with PGA symptoms reported some overlap in medical comorbidities and symptom expression as those with combined PGA and vulvodynia and those with vulvodynia symptoms alone; however, there were also a number of significant differences in their associated physical symptoms. These studies indicate that PGA symptoms have negative consequences for the psychosocial functioning of affected women. As such, future research and clinical care may benefit from a biopsychosocial approach to PGA symptoms. These studies highlight areas for more targeted research, including the role of catastrophizing in PGA symptom development and maintenance, and the potential conceptualization of both PGA and vulvodynia (and potentially other conditions) under a general umbrella of ‘genital paraesthesias’ (i.e., disorders characterized by abnormal sensations, such as tingling and burning).
