From question-behaviour effects in trials to the social psychology of research participation

The ‘question-behaviour effect’ (QBE) has attracted much recent attention within health psychology, where it has also been referred to as the ‘mere measurement’ effect. There are other conceptualisations of similar phenomena in related disciplines. This paper explores the implications of the QBE for the safety of inferences about intervention effectiveness within the context of randomised controlled trials evaluating health behaviour change interventions. It draws attention to poorly understood mechanisms by which bias is introduced with conventional thinking about trial design and analysis. The threat to valid inference on intervention effectiveness posed by the QBE applies even when its effects are small and regardless of the specific content of the QBE. The nature of the resulting bias does not fit well within existing bias classification schemes, such as that proposed by the Cochrane Collaboration. The QBE is one possible consequence of research participation and it is suggested that the social psychology of research participation is very much underdeveloped. Possible future directions for health psychology research in this area are considered.     

An improved method for evaluating ideal standards in self‐perception and mate preferences

The aim of the study was to improve the methodology for measuring ideals of self‐perception and mate preferences. The Ideal Standards Model (ISM; Fletcher, Simpson, Thomas & Giles, 1999) was used as a basis for development of the scale. It was further modified by adding a number of items from previous studies. Data were collected from 223 participants, aged 19 to 27 years. The results suggested that a modified five‐factor version of the ISM is an appropriate method for evaluation of ideal characteristics. The five factors are warmth/ trustworthiness, status/ resources, intelligence, social skills and physical attractiveness.     

Job satisfaction among Swedish soldiers: Applying the Job Characteristics Model to newly recruited military personnel

A professional military organization was introduced in Sweden in 2010. This means that the Swedish Armed Forces (SAF) need to attract and employ soldiers, and to retain them within the organization. This scenario creates new types of challenges in manning the organization. The transition to an all-volunteer force puts job satisfaction in focus in order to retain personnel. This cross-sectional study of the relations between working conditions and job involvement among 300 recently employed soldiers showed that the dimensions of the Job Characteristics Model related significantly to job satisfaction and work motivation and (negatively) to turnover intentions from the SAF. The results further showed that all the critical psychological states contributed independently to the variance in the outcome variables.     

Piezoelectric and electromechanical coupling constants for GaxIn1-xSb semiconducting alloys

The compositional dependence of piezoelectric stress and strain constants and electromechanical coupling coefficient of Ga_xIn_1-xSb have been investigated. The calculations were performed using a pseudopotential approach combined with the Adachi model where different concepts of ionicity are considered. Our results are compared with the available data and found to be in good accord with each other. Our findings show that as the Ga content varies, the piezoelectric and related constants and transport properties of the alloy system of interest are significantly affected.     

Resilience in families in which a child is bullied

The aim of this study was to identify family resilience characteristics in families in which a child has been bullied, in the Western Cape province of South Africa. Forty-eight mothers represented their families and completed a biographical questionnaire containing an open-ended question, and seven self-report questionnaires. Results from the qualitative data showed that most of the families coped with the bullying by talking to a teacher, principal or the governing body, or by giving advice to the child who had been bullied. The quantitative results highlighted the quality of family communication, the fortitude and durability of the family unit, and the family's emphasis on being together. These findings can be utilised in interventions to strengthen families finding themselves in a similar crisis.     

What role does neuroticism play in the association between negative job characteristics and anxiety and depression?

Many studies have established an association between job characteristics and anxiety and depression and noted that personality characteristics such as neuroticism likely play a role in creating or modifying these associations. Few studies, however, have explicitly tested or compared these possible alternative roles. In this study, we tested several specific hypotheses about neuroticism and its effects on job characteristics, anxiety and depression and their association in a series of structural equation models. Participants (N = 372) completed the Big Five Inventory, Job Contents Questionnaire and General Health Questionnaire. We tested (a) whether neuroticism is likely to be an important confounder of the association between job characteristics and anxiety and depression and (b) whether neuroticism moderates the association between job characteristics and anxiety and depression. Results indicated large attenuations by neuroticism of the association between job characteristics and anxiety and depression but there remained significant effects of psychological demands on anxiety, and social support on depression independent of neuroticism. Evidence was also found for interaction effects between neuroticism and decision latitude, with those lower in neuroticism being at higher risk for depression under conditions of low control.     

A Geographic Analysis of Chronically Homeless Adults Before and After Enrollment in a Multi-Site Supported Housing Initiative: Community Characteristics and Migration

The current study examined the community characteristics and migration of chronically homeless adults before and after entry into a multi-site supported housing initiative. A total of 394 participants were geocoded at baseline and 12-month follow up. Data from geographic information systems indicate that the median distance participants traveled from their last residence to their residence 1 year after program entry was 4.6 miles and 12% of participants traveled more than 100 miles. Participants moved into communities with higher population densities, larger proportions of Whites, and smaller proportions of Blacks following their entry into supported housing, but continued to live in communities with higher crime rates, lower education levels, and lower income levels then the state average. At 12 months, Black participants residing in communities with higher population densities and larger Black populations reported higher social support and lower subjective distress. This underscores the importance of considering client preferences in housing. Together, these findings suggest that supported housing programs may be successful in finding housing for homeless clients, but are not placing them in improved communities. Special attention may also be needed for some clients who travel long distances between residences.     

Characteristics of intrusive memories in a community sample of depressed, recovered depressed and never-depressed individuals

An accumulating body of evidence has revealed that intrusive autobiographical memories of negative events play a role in depression. Despite increasing understanding of the phenomenological experience of these memories, previous research in this area has been conducted in either nonclinical samples, or in clinical samples without an adequate control group. This study aimed to replicate and extend findings with dysphoric samples by comparing the content and characteristics of intrusive memories in clinically depressed (n = 25), recovered (n = 30) and never-depressed (n = 30) participants. Participants completed mood measures, and a battery of self-report questionnaires that indexed intrusive memory frequency, avoidance and characteristics. Intrusive memories were common and shared strikingly similar characteristics across the three groups. The key finding was that depressed participants reported higher levels of intrusion-related distress, associated emotions (especially sadness and helplessness), interference as a result of the memories and memory vividness compared to the never-depressed group. Despite similar levels of intrusion, there were group differences in avoidance such that depressed participants reported higher levels of avoidance than the never-depressed group. These results provide further support for the proposal that clinical interventions for depression could usefully incorporate components that aim to reduce intrusive autobiographical memories and target avoidance strategies.     

Designated as Dangerous: Characteristics of Sex Offenders Subject to Post‐Sentence Orders in Australia

The earliest characterisation of Australian sex offenders subjected to post‐sentence legislation is presented. Demographic, developmental, clinical, and criminal characteristics were obtained for sex offenders under post‐sentence orders in Western Australia, New South Wales, and Victoria. Data on 50 offenders were recorded from psychological and psychiatric risk assessment reports statutorily required at the initiation of post‐sentence legal proceedings. The findings describe a group of demonstrably dangerous men who exhibited an early onset of sexual offending, high rates of mental disorder, sexual deviance, and antisociality. Their developmental histories are characterised by early deprivation, disadvantage, abuse, early exposure to substance abuse, and social and psychological dislocation. These offenders present a conundrum to criminal justice agencies. They are an objectively unfortunate group and have engaged in significantly harmful behaviours. However, the early onset of their offending suggests that early intervention services, such as those offered by mental health professionals, have a critically important role to play in any effort to alter offending trajectories such as those exhibited in this sample. A paradigm shift in public policy from a post hoc model to a well‐resourced preventative and public health approach to the problem of sexual violence is proposed. Broad treatment implications are also considered.
