This study investigates the application of consumer behaviour theory to young Australian adults’ voting decision-making. Previous decision-making studies identified constructs of subjective knowledge, involvement, information seeking, satisfaction, confidence, and stability as key factors in voting decision-making. This research tests the relationship that these factors have with the consumer behaviour concept of usage. A new concept, commitment to vote, is also considered for Australia’s compulsory voting context. Data were gathered from a sample of 257 Australian citizens between the ages of 18 and 25. Exploratory factor analysis produced nine factors, and MANOVA and ANOVA were used to test the differences between three usage groups: voluntary users, involuntary users, and never trieds. The results illustrate that usage has a significant influence on information seeking, commitment to voting, satisfaction with voting choice, and stability in voting decision-making. Therefore, usage is a key element in voter decision-making and needs to be included in future studies.

Objective: A new instrument, the Adolescent Depression Treatment Satisfaction Questionnaire (ADTSQ) was devised to measure the consumer satisfaction of depressed adolescents and their parents. The objectives of the paper were to present the psychometric proper ties ofthe ADTSQ and to investigate the relative consumer satisfaction with cognitive-behavioural therapy (CBT), sertraline (SRT) and a combined treatment of CBT and SRT (COMBINED) for the treatment of adolescent depression. In addition, participants were asked to rank their most preferred treatment from the following approaches: medication, individual counselling, group program and family therapy.Method: Thirty-eight adolescents with a unipolar depressive disorder and 37 parents who participated in a randomized clinical trial of CBT versus SRT versus COMBINED completed the ADTSQ following the completion of acute treatment.Results: The ADTSQ was found to have high internal consistency and exploratory factor analysis detected three underlying factors. High levels of consumer satisfaction were reported by both adolescents and parents in all three treatments. Those treated with CBT treatments reported higher levels of skill acquisition than those treated with SRT. Of the four treatment approaches, most parents and adolescentsrated individual counsellingas their first preference.Conclusions: The ADTSQ is a useful measure of consumer satisfaction for depressed adolescents and their parents. CBT, SRT and COMBINED were shown to have high consumer satisfaction with CBT's higher skills training content reflected in the participants' reports. Individual counselling was perceived as the most favourable choice of treatment for adolescent depression. Although limitations associated with the measurement of consumer satisfaction and of the study are acknowledged, it is recommended that the inclusion of consumer satisfaction measures be considered in clinical trials that examine treatment efficacy.

Park agencies must plan to accommodate a diversity of visitors in order to satisfy visitor expectations and encourage future visitation. This study applies a market segmentation approach to develop a visitor typology that is effective across a broad spectrum of parks and applicable to a range of priorities, both strategic and operational, within park management agencies. Over a four-year period, data was sourced from over 11,000 interviews conducted at 33 diverse Australian national and metropolitan parks managed by the agency Parks Victoria. Factor analysis and cluster analysis was used to identify seven distinct visitor segments on the basis of numerous variables including, crucially, benefits sought. The applied and theoretical contributions of this study to the parks literature are discussed.

The present study examined the presentation of autistic traits in a large adult population sample (n = 2,343). Cluster analysis indicated two subgroups with clearly distinguishable trait profiles. One group (n = 1,059) reported greater social difficulties and lower detail orientation, while the second group (n = 1,284) reported lesser social difficulties and greater detail orientation. We also report a three-factor solution for the autism-spectrum quotient, with two, related, social-themed factors (Sociability and Mentalising) and a third non-social factor that varied independently (Detail Orientation). These results indicate that different profiles of autistic characteristics tend to occur in the adult nonclinical population. Research into nonclinical variance in autistic features may benefit by considering social- and detail-related trait domains independently.

Empowerment refers to an individual's feelings of being able to manage the challenges of the cancer experience and of having a sense of control over one's life. However, empowerment questionnaires that have been validated for the cancer setting are lacking. The objective of this study was to validate scales from the Health Education Impact Questionnaire (heiQ), which assesses the effects of health education programs among individuals with chronic conditions. The heiQ scales Social integration and support, Health service navigation, Constructive attitudes and approaches, Skill and technique acquisition, and Emotional distress were identified as key dimensions of empowerment for the cancer context.

In March 2011, the United Kingdom's (UK's) Government launched five Public Health Responsibility Deal Networks to address public health priorities. The Networks used voluntary partnerships to influence peoples' choice architecture to move them toward healthier behaviors. The purpose of this research was to conduct an exploratory study of diverse stakeholders' perspectives about perceived responsibility and accountability expectations to improve food environments in England through the Food Network partnerships. A purposive sample of policy elites (n=31) from government, academia, food industry and non-government organizations sorted 48 statements related to improving food environments in England. Statements were grounded in three theoretical perspectives (i.e., legitimacy, nudge and public health law). PQMethod 2.33 statistical software program used factor analysis to identify viewpoints based on intra-individual differences for how participants sorted statements. The results revealed three distinct viewpoints, which explained 64% of the variance for 31 participants, and emphasized different expectations about responsibility. The food environment protectors (n=17) underscored government responsibility to address unhealthy food environments if voluntary partnerships are ineffective; the partnership pioneers (n=12) recognized government-industry partnerships as legitimate and necessary to address unhealthy food environments; and the commercial market defenders (n=1) emphasized individual responsibility for food choices and rejected government intervention to improve food environments. Consensus issues included: protecting children's right to health; food industry practices that can and should be changed; government working with industry on product reformulation; and building consumer support for economically viable healthy products. Contentious issues were: inadequacy of accountability structures and government inaction to regulate food marketing practices targeting children. We conclude that understanding different viewpoints is a step toward building mutual trust to strengthen accountability structures that may help stakeholders navigate ideologically contentious issues to promote healthy food environments in England.

Purpose– The purpose of this paper is to seek to assess whether online commercial panel volunteering can be segmented based on their motivations, using the volunteer functions inventor. The authors also investigate whether segments exist which differ in demographic characteristics.Design/methodology/approach– The authors survey 484 Australian online panel volunteers using a adapted version of the 30 item of the volunteer function inventory (VFI) scale developed by Clary et al. (1998). Data were analysed using confirmatory factor analysis (CFA) and cluster analysis, as well as ANOVA and χ2 test comparisons of demographics between clusters.Findings– CFA verifies that the VFI scale is suitable instrument to gauge online participants’ motivations. Cluster analysis produced a five-cluster solution, where respondents with low motivations overall comprised the largest grouping. Segments are interpreted by assessing the difference between the total sample average and the segment profile. The examination also identifies that the only demographic factor that varies across the five clusters is “respondents” employment status”.Research limitations/implications– Future research could explore if differences in segments result in differences in online participation. The high number or respondents with low motivations may explain the relatively high levels of churn that take place within online panels and as a result panel operators would need to continually attract new members. Further research could also investigate whether the levels of motivation change over time and if so what effect such variation would produce on respondents’ retention.Originality/value– Research on online panel respondents’ motivation is still limited and investigating online panellists’ motivation as volunteers is very important as it unveils, as in the study herein reported, that alternative types of respondents may be driven by different factors when joining an online panel (or completing a given survey). Recruitment strategies could, therefore, be shaped to suit the motivation of the different segments. By refining the matching between volunteers’ profiles and their motivation, managers could improve how volunteers are recruited, managed and retained.

Negative attitudes towards insulin are commonly reported by people with type 2 diabetes mellitus (T2DM) and can act as a barrier to timely insulin initiation. The Insulin Treatment Appraisal Scale (ITAS) is a widely used 20-item measure of attitudes towards insulin. While designed for completion by both insulin using and non-insulin using adults with T2DM, its psychometric properties have not been investigated separately for these groups. Furthermore, the total score is routinely reported in preference to the published two-factor structure (negative/positive appraisals). Further psychometric validation of the ITAS is required to examine its properties.

This study examines the relationships between spirituality in the workplace, organizational commitment and job performance measured in terms of key performance indicators (KPIs) based on a sample of 376 academic staff at Universiti Sains Malaysia (USM). The methods used in the study are factor analysis and multiple regression analysis. Three factors are found to explain organizational commitment: affective commitment, continuance commitment and normative commitment. Affective and normative commitments are positively influenced by workplace spirituality, which is explained by three factors: alignment between organizational and individual values; sense of enjoyment at work and contribution to community; and opportunity for inner life. The study also finds that neither high commitment nor workplace spirituality among academic staff necessarily manifest in high KPIs. Instead, other staff background variables appear to have more influence on job performance, such as gender, stream, age and rank.

Objective: In 2011, the United Kingdom launched five Public Health Responsibility Deal Networks inspired by ‘nudge theory’ to facilitate healthy-lifestyle behaviors. This study used Q methodology to examine stakeholders’ views about responsibility and accountability for healthy food environments to reduce obesity and diet-related chronic diseases. Design: A purposive sample of policy elites (n=31) from government, academia, food industry and civil society sorted 48 statements grounded in three theoretical perspectives (i.e., legitimacy, nudge and public health law). Factor analysis identified intra-individual statement sorting differences. Results: A three-factor solution explained 64 percent of the variance across three distinct viewpoints: food environment protectors (n=17) underscored government responsibility to address unhealthy food environments; partnership pioneers (n=12) recognized government-industry partnerships as legitimate; and the commercial market defenders (n=1) emphasized individual responsibility for food choices and rejected any government intervention. Conclusions: Building trust and strengthening accountability structures may help stakeholders navigate differences to engage in constructive actions. This research may inform efforts in other countries where voluntary industry partnerships are pursued to address unhealthy food environments.

The purpose of this study was to examine the construct validity of the WOrk-reLated Flow inventory (WOLF; Bakker, 2008). This instrument was administered to 711 men and women who were working in Queensland, Australia. The results from the confirmatory factor analysis showed that the WOLF has moderately acceptable construct validity, with the three-factor model being a borderline fit to the data. Tests of the convergent validity of the WOLF yielded satisfactory results. However, the analysis of the discriminant validity of the WOLF showed that the instrument poorly discriminated between work enjoyment and intrinsic work motivation. Follow-up exploratory factor analysis, using recommended procedures for determining the number of factors to extract, revealed a two-factor solution, with the work enjoyment and intrinsic work motivation items loading on the same factor. Drawing on literature on psychological flow and motivation, as well as the findings of the present study, questions are raised over the adequacy of the conceptual basis of the three-factor model of work-related flow, the discriminant validity of the WOLF subscales, and the appropriateness of the wording of several of this measure's items. Using alternative methods and measures to investigate flow in work settings is recommended.

In eyewitness studies as in actual investigations, a minority of children generate numerous false (and sometimes incredulous) allegations. To explore the characteristics of these children, we reinterviewed and administered a battery of tasks to 61 children (ages 4-9 years) who had previously participated in an eyewitness study where a man broke a "germ rule" twice when he tried to touch them. Performance on utilization, response conflict (Luria tapping), and theory of mind tasks predicted the number of false reports of touching (with age and time since the event controlled) and correctly classified 90.16% of the children as typical witnesses or exuberant (more than 3) false reporters. Results of a factor analysis pointed to a common process underlying performance on these tasks that accounted for 49% of the variability in false reports. Relations between task performance and testimony confirmed that the mechanisms underlying occasional intrusions are different from those that drive persistent confabulation and that deficient cognitive control fuels young children's exuberant false reports.

Understanding subjective wellbeing (SWB) at the population level has major implications for governments and policy makers concerned with enhancing the life quality of citizens. The Personal Wellbeing Index (PWI) is a measure of SWB with theoretical and empirical credentials. Homeostasis theory offers an explanation for the nature of SWB data, including the distribution of scores, maintenance and change over time. According to this theory, under normal conditions, the dominant constituent of SWB is Homeostatically Protected Mood (HPMood), which is held within a genetically determined range of values around a set-point. However, in extreme circumstances (e.g., financial hardship, chronic illness), HPMood may dissociate from SWB, as cognitive/emotional reactions to the cause of homeostatic challenge assume control over SWB. This study investigates two groups as people scoring in the positive range for SWB and people who are likely to be experiencing homeostatic defeat/challenge. We test whether the reduced influence of HPMood on SWB due to homeostatic defeat has implications for the validity of SWB measurement. Participants were 45,192 adults (52 % female), with a mean age of 48.88 years (SD = 17.35 years), who participated in the first 23 surveys of the Australian Unity Wellbeing Index over the years 2001–2010. Multiple regression analysis, multiple group confirmatory factor analysis, and Rasch modelling techniques were used to evaluate the psychometric performance of the PWI across the two groups. Results show that while the PWI functioned as intended for the normal group, SWB in the challenged group was lower across all PWI domains, more variable, and the domain scores lacked the strength of inter-correlation observed in the normal, comparison group. These changes are consistent with predictions based on homeostasis theory and one major implication of the findings is that SWB measures may not function equivalently across the entire spectrum of possible domain satisfaction scores.
