Parenting Assessed by Observation versus Parent-report: Moderation by Parent Distress and Family Socioeconomic Status

Assessment of parenting frequently relies on parent self-report despite well-documented discrepancies between this methodology and observational measures. In the current study, we investigated patterns of disagreement between self-reported and observational measures of positive parenting and negative parenting with 102 dyads of parents and 4–6 year-old children. Specifically, we tested whether differences in parent distress and family socioeconomic status (SES) moderated the association between self-reported and observed parenting. Results showed significant interactions with less agreement between self-report and observational measures among parents reporting higher levels of distress and among families from lower SES backgrounds. Effects were more pronounced in models of negative parenting than those of positive parenting. Findings suggest that two factors relevant to parenting quality, emotional distress and SES, predict meaningful differences in manner of parent-report relative to observational measures. We discuss implications for the extant literature and for future efforts regarding effective and efficient parenting measurement.     

The role of risk and protective factors in predicting symptomatology in adolescent self-identified children of alcoholic parents

Tested a stress process model for predicting mental health symptoms in children of alcoholics (COAs). Stress and mental health measures were completed twice over a 3-month period by 145 high school students, 43 of whom self-identified as COAs. Using structural equation modeling, a stress process model for predicting mental health symptoms in children provided a good fit to the data. COA status was related to higher levels of negative and lower levels of positive events. In turn, positive and negative life events were found to have an immediate, but not a longitudinal, direct effect on adolescent symptomatology.     

What role does substance use play in the social world of Australian people who have experienced homelessness? A critical realist mixed‐methods exploration

Substance use is prevalent amongst Australians who have experienced homelessness, but the social impacts of using substances amongst this group are poorly understood. This study uses a relational and critical realist approach to understand the role of substance use on the social lives of people with lived experience of homelessness. A mixed‐methods design was used to explore this question and assess the experiences of people who have exited homelessness. Recruiting across services catering to marginalised populations, 110 participants completed a cross‐sectional survey. Findings showed substance use both socially connected and disconnected participants, and that attempting abstinence required participants to negotiate and alter their social networks. To participants, being a substance “user,” or “non‐user,” was a social identity that they actively negotiated to facilitate competing social, psychological and material/embodied needs. Participants chose to engage and not engage with others to craft a social identity they valued, which had the sometimes‐negative side‐effect of limiting potential relationships, leaving users feeling isolated from their non‐users and a continued imperative to keep using. The impacts of substance use on social networks were similar for currently and formerly homeless participants, suggesting transitioning into housing may not immediately prompt a reduction in substance use or influence from substance‐using peers. Interventions with substance users with lived experience of homelessness would benefit from taking a social identity approach that incorporates an understanding of the material/embodied aspects of addiction to provide a holistic model of care that best supports the relational needs of the client.     

Testing the ruler with item response theory: increasing precision of measurement for relationship satisfaction with the Couples Satisfaction Index.

The present study took a critical look at a central construct in couples research: relationship satisfaction. Eight well-validated self-report measures of relationship satisfaction, including the Marital Adjustment Test (MAT; H. J. Locke & K. M. Wallace, 1959), the Dyadic Adjustment Scale (DAS; G. B. Spanier, 1976), and an additional 75 potential satisfaction items, were given to 5,315 online participants. Using item response theory, the authors demonstrated that the MAT and DAS provided relatively poor levels of precision in assessing satisfaction, particularly given the length of those scales. Principal-components analysis and item response theory applied to the larger item pool were used to develop the Couples Satisfaction Index (CSI) scales. Compared with the MAS and the DAS, the CSI scales were shown to have higher precision of measurement (less noise) and correspondingly greater power for detecting differences in levels of satisfaction. The CSI scales demonstrated strong convergent validity with other measures of satisfaction and excellent construct validity with anchor scales from the nomological net surrounding satisfaction, suggesting that they assess the same theoretical construct as do prior scales. Implications for research are discussed.     

Purity, Privacy and Procreation: Constructions and Experiences of Sexual and Reproductive Health in Assyrian and Karen Women Living in Australia

It is widely recognised that sexual and reproductive health services are underutilised by culturally and linguistically diverse migrant communities, leading to risk of poor health outcomes. This study examined the constructions and experiences of reproductive and sexual health, and associated services, in Assyrian and Karen women who had arrived in Australia as refugees. Forty two women, across a range of age groups and marital status, participated in five focus groups, with thematic analysis and positioning theory used to analyse the results. Two major themes were identified. The first, the ??Premarital Chastity Imperative?? centres on the cultural prohibition of coital hetero-sex before marriage, and taboos associated with same-sex relationships. This has implications for unmarried women??s access to sexual health services, such as contraception, cervical screening, and abortion; prohibition of sex education and communication about sex; and lack of recognition of non-heterosexual identities. The second theme, ??Marital Sex and Reproductive Imperative??, positioned coital sex and motherhood as mandatory within marriage, and was associated with women??s inability to refuse marital sex, limited knowledge about contraception and sexual pain, acceptance of fertility services, as well as lack of recognition of post-natal depression. It is concluded that health care workers need to be aware of cultural constructions of sex and sexuality, as well as the construction of gendered roles within heterosexual relationships, when designing and offering sexual health services to non English speaking or migrant communities.     

Tuned for the future: Intentions are only accessible when a retrieval opportunity is near

The intention-superiority effect describes faster reaction times for stimuli related to an intention than for more neutral material during the retention interval. Some authors have interpreted the effect in terms of a more persistent activation of intention-related material. However, typically participants are instructed to realize the intention immediately after completing the task in which reaction times are assessed (e.g., a recognition task) in order to yield the intention-superiority effect. Thus, the reaction-time task is also associated with a retrieval context. We tested whether the proximity of a retrieval opportunity affects the intention-superiority effect by manipulating whether or not a recognition task indicated a retrieval opportunity. We observed an intention-superiority effect only if the task itself was a meaningful cue for a near retrieval opportunity. This finding indicates that even short-term-delayed intentions flexibly become more or less accessible, depending on the proximity of a retrieval opportunity. We further demonstrated that the intention-superiority effect is not restricted to motor tasks, but is also found for monitoring tasks when the task realization has personally relevant consequences (replicating Schult & Steffens, Memory & Cognition, 39, 1487–1495, 2011).     

Impact of Client Suicide on Psychologists in Australia

Objective

This research aimed to assess the frequency and impact of client suicides on psychologists in Australia.

Method

Participants were 178 psychologists who completed an online self‐report questionnaire concerning the frequency of occurrence and impact of client suicide.

Result

Fifty six (31.5%) participants reported one or more client suicides. Psychologists with more years of experience reported more client suicides. Participants who had experienced a client suicide reported a range of emotional, cognitive and behavioural reactions as well as professional impacts. Ratings of responsibility, preventability and predictability of a client suicide were associated with emotional and/or professional impacts. Beneficial coping responses included talking to supervisors and colleagues, recognising the psychologist is not responsible and having increased acceptance of a client suicide.

Conclusions

The findings have important implications for training, workplace practices and research.
