To use or not to use: Expanding the view on non-addictive psychoactive drug consumption and its implications

Proposing a change to the view on psychoactive drug use in non-addicts touches a sensitive issue because of its potential implications to addiction prevention, therapeutic practice, and drug policy. Commentators raised nine questions that ranged from clarifications, suggested extensions of the model to supporting data previously not regarded, to assumptions on the implications of the model. Here, we take up the suggestions of the commentators to expand the model to behavioral addictions, discuss additional instrumentalization goals, and review the evidence from laboratory animal studies on drug instrumentalization. We consider further the role of sociocultural factors and individual development in the establishment in drug instrumentalization and addiction. Finally, we clarify which implications we think this model may have. We conclude that drug instrumentalization theory can be further applied to other behaviors but will require a sensitive debate when used for drug and addiction policy that directly affects prevention and treatment.     

How changes in subjective general health predict future time perspective,and development and generativity motives over the lifespan

In this study, we used the lifespan theories of selection optimization and compensation (SOC) and the socio‐emotional selectivity theory (SST) to integrate the disengagement and activity perspectives on aging and to explain intra‐individual changes in work motivation. A two‐wave longitudinal survey study was conducted among 600 Dutch university employees to test relations between intra‐individual changes in subjective general health, future time perspective (FTP), and generativity and development motives. In line with the two lifespan theories, two processes were found. First, consistent with the disengagement perspective on aging, losses in subjective general health negatively predicted open‐ended FTP, and open‐ended FTP was positively associated with an increase in growth motives. Secondly, consistent with the activity perspective on aging, losses in subjective general health positively predicted limited FTP, and limited FTP was positively associated with an increase in generativity motives. In addition, initial open‐ended FTP predicted future open‐ended FTP through a change in subjective general health. Finally, these relations were found to differ across age groups, and thus over the lifespan. More specifically, losses in subjective general health and increases in limited FTP particularly result in lower development motives and higher generativity motives among middle‐aged workers, indicating that interventions aimed at preventing losses in health are probably most effective for maintaining development motives in this group.     

A nonparametric method to analyze interactions: The adjusted rank transform test

Experimental social psychologists routinely rely on ANOVA to study interactions between factors even when the assumptions underlying the use of parametric tests are not met. Alternative nonparametric methods are often relatively difficult to conduct, have seldom been presented into detail in regular curriculum and have the reputation - sometimes incorrectly - of being less powerful than parametric tests. This article presents the adjusted rank transform test (ART); a nonparametric test, easy to conduct, having the advantage of being much more powerful than parametric tests when certain assumptions underlying the use of these tests are violated. To specify the conditions under which the adjusted rank transform test is superior to the usual parametric tests, results of a Monte Carlo simulation are presented.     

Evidence Searching for Evidence-based Psychology Practice

There is an increased awareness of evidence-based methodology among psychologists, but little exists in the literature about how to access the research. Moreover, the prohibitive cost of this information combined with limited time are barriers to the identification of evidence to answer clinical questions. This article presents an example of a question worked though in an evidence-based way. Methods are highlighted, including distinguishing background and foreground questions, breaking down questions into searchable statements, and adapting statements to suit both the question being asked and the resource being searched. A number of free, evidence-based resources are listed. Knowing how and where to access this information will enable practitioners to more easily use an evidence-based approach to their practice.     

Donation to charity and purchase of cause‐related products: The influence of existential guilt and experience

Charity donation is an important prosocial behaviour that is often generated/strengthened by emotional stimuli from advertising. A similar strategy is often used to trigger the purchase of cause‐related products. The two activities represent direct and indirect methods of financial support and are important topics for researchers and practitioners. Charity donation and purchase of cause‐related products are typically investigated on the basis of different theoretical backgrounds; therefore, they are almost never directly compared with each other. However, the two share some similarities from the perspectives of the donor/buyer and the donation recipient. This article aims to analyse how direct and indirect donation behaviours are influenced by the same emotional stimulus (existential guilt generated by a visual advertisement). In parallel, this article examines the possible moderation effect of similar past behaviours. The study is performed by surveying 374 respondents in Lithuania. Results confirmed that the same emotion (existential guilt) had a direct positive impact on the intention towards both studied behaviours. However, the moderation effect of experience was observed only in the relationship between existential guilt and the intention to donate to charity, signalling the difference in its influence on the two behaviours. These findings enrich the knowledge of the similarities and differences between direct (donating to charity) and indirect (purchasing cause‐related products) donation behaviours. Additionally, it fills in the knowledge gap regarding the relation between the intentions of prosocial behaviours and existential guilt as an advertising appeal.     

Culture, trauma, and wellness: a comparison of heterosexual and lesbian, gay, bisexual, and two-spirit native americans

In a community-based sample of urban American Indian and Alaska Native adults, 25 lesbian, gay, bisexual, and two-spirit participants were compared with 154 heterosexual participants with respect to sociodemographic characteristics, Native, cultural participation, trauma, physical and mental health, and substance use. Compared with their heterosexual counterparts, two-spirit participants reported higher rates of childhood physical abuse and more historical trauma in their families, higher levels of psychological symptoms, and more mental health service utilization. Two-spirit participants reported differences in patterns of alcohol use and were more likely to have used illicit drugs other than marijuana. Discussion and recommendations for health promotion interventions and future research are presented in consideration of an "indigenist" health model and the multiple minority status of two-spirit people.     

Psychometric properties of the Self-Perception Profile for Children in a biracial cohort of adolescent girls: the NHLBI Growth and Health Study

The National Heart, Lung, and Blood Institute Growth and Health Study (NGHS) is an epidemiologic study of 1,213 Black and 1,166 White girls (ages 9-10) of risk factors for obesity. NGHS used Harter's Self-Perception Profile for Children (SPPC) to measure domain-specific competence and overall self-worth. This report reviews the psychometric properties of the SPPC in this biracial cohort at baseline and Year 3 visits (ages 11-12). Simple structure yielding unique components for each of the SPPC domains was obtained for White but not Black girls, whether analyzed overall or by parental education level. Internal consistency was higher for White girls in both years. The lack of simple structure was reflected in the higher correlations among the subscales for Black girls. The structure and internal consistency improved in Year 3 for Black girls, indicating that the physical appearance and athletic competence domains were not yet fully differentiated at baseline. Readers should be cautious, however, when interpreting the SPPC in young Black girls.     

A Critical Appraisal of Self-Report Defense Mechanism Measures

Defense mechanisms have been a source of both fascination and frustration for most personality researchers because they are conceptually intriguing but their assessment is often problematic. To aid personality researchers in integrating defense mechanism theory into personality research, we review and critique the major existing self-report defense mechanism measures: the Coping and Defending Scales (Joffe & Naditch, 1977); the Defense Mechanisms Inventory (Gleser & Ihilevich, 1969); the Life-Style Index (Plutchik, Kellerman, & Conte, 1979); and the Defense Style Questionnaire (Bond, Gardner, Christian, & Sigal, 1983). We conclude that no self-report measure adequately assesses the defining features of defense mechanisms. We offer a number of person and situation variables that must be considered when evaluating any defense mechanism measure, and we conclude that the comprehensive assessment of defense mechanism use will likely require measures obtained from multiple sources.     

Strengths use and deficit correction in organizations: development and validation of a questionnaire

Although the positive psychology tradition emphasizes the importance of a balanced approach regarding individual strengths and weaknesses, there is no valid instrument to measure these phenomena in organizations. The purpose of the present studies is to develop and validate an instrument that measures four dimensions, namely perceived organizational support (POS) for strengths use, POS for deficit correction, strengths use behaviour, and deficit correction behaviour. In study 1 and 2, the Strengths Use and Deficit COrrection (SUDCO) questionnaire was developed and tested for its factor structure, reliability, and convergent and criterion validity in two samples of South African employees (N = 338 and N = 361, respectively). In study 3, the convergent and criterion validity of the SUDCO were examined in a sample of Dutch engineers (N = 133). Results indicated that the intended dimensions of strengths use and deficit correction can be measured reliably with 24 items and showed convergent validity. Moreover, POS for strengths use and strengths use behaviour correlated positively with self- and manager-ratings of job performance, supporting the criterion validity of these scales. As expected, POS for deficit correction and deficit correction behaviour were unrelated to the performance ratings.     

Self- and Expert-Reported Emotion Inhibition: On the Utility of Both Data Sources

Psychodynamic theorists often believe clinical judges to be the best source of personality data. Contemporary personality theorists, on the other hand, treat individuals' responses to items on personality tests as the most appropriate source of personality data. In personality domains such as emotion inhibition, or defensiveness, a combination of these two data sources may provide valuable, albeit different, information. To demonstrate this postulate, participants completed a self-report measure of emotion inhibition, underwent a stressful interpersonal task during which blood pressure reactivity was recorded, and then were rated for observed emotion inhibition. As expected, observational and self-reports of emotion inhibition appeared to assess differing tendencies, but both additively predicted cardiovascular reactivity. Self- and expert-reports of personality characteristics may often complement each other, and when these measures are informed by empirical/psychometric considerations they can both contribute to the understanding of areas such as psychophysiological reactivity.
