Haloperidol-induced Mood and Retrieval of Happy and Unhappy Memories

The present study investigated the effect of haloperidol-induced mood in normal healthy male volunteers on the retrieval of memories of real-life personal experiences using a between-subjects double-blind design. Forty subjects were required to retrieve past real life experiences associated with a series of stimulus words following administration of a single oral dose of 5mg haloperidol or placebo. The experiences were subsequently rated by subjects for their happiness felt at the time of the original experience. A significant decline in self-reported hedonic tone was observed in subjects given haloperidol. In addition, subjects on placebo recalled a significantly greater percentage of happy memories than subjects who were on haloperidol; a trend for a reverse pattern was observed for unhappy memories. The effects of the drug on the retrieval of memories were only in part mediated by the decline in hedonic tone scores. The effects of haloperidol are interpreted in terms of drug-induced dysphoria.     

Do personality factors predict job satisfaction?

Two studies investigated the relationships between personality traits and aspects of job satisfaction. In Study 1, job applicants (n=250) completed the Eysenck Personality Profiler and the Work Values Questionnaire (WVQ), which requires respondents to rate various work-related facets according to the extent to which they contribute to their job satisfaction. These facets were combined into two composites (hygiene and motivator) based on previous research. The three personality superfactors accounted for a small percentage of the variance in importance ratings (about 5%). In Study 2, employees (n=82) completed a measure of the ‘Big Five’ personality traits and the Job Satisfaction Questionnaire (JSQ), which assesses both what respondents consider as important in their work environment as well as their satisfaction with their current job. Importance ratings were again combined into two composites while job satisfaction ratings were factor analyzed and three factors, differentiated along hygiene versus motivator lines, emerged. Personality traits again accounted for a small percentage of the total variance both in importance ratings and in levels of job satisfaction. It is concluded that personality does not have a strong or consistent influence either on what individuals perceive as important in their work environment or on their levels of job satisfaction.     

Creative Fixation is No Laughing Matter: The Effects of Funny and Unfunny Examples on Humor Production

How do people come up with humorous ideas? In creative cognition research, exposure to good examples sometimes causes fixation (people get “stuck” on the examples) but other times sparks inspiration (people's responses are more creative). The present research examined the effects of funny and unfunny examples on joke production. A sample of 175 adults read scenarios that they completed with funny responses. All participants were instructed to be funny, but before responding they read (a) funny responses as examples of good responses to emulate, (b) unfunny responses as examples of poor responses to avoid, or (c) no examples. The participants’ own responses were rated for funniness and for similarity to the example responses, and response times were recorded. Reading either funny or unfunny examples, compared to no examples, caused people to come up with funnier jokes. Similarity to the examples was low in all conditions, so fixation was relatively modest, but people who saw unfunny examples spent more time coming up with their responses. Taken together, the findings support the growing literature showing that examples are often inspiring rather than constraining, and they imply that good and bad examples spark creative thought via different paths.     

Measurement of Sense of Community Within the Sphere of City1

Based on a deductive process, several objective items were developed to measure people's sense of community with their city of residence. An item analysis produced a 17-item scale, which was then evaluated for homogeneity and external validity in three studies using telephone interviews on random samples in Alabama and South Carolina. Of seven hypotheses that were tested, six received support. Results described the scale as internally reliable and unidimensional, and the scale differentiated between people who differed in terms of demographics, home ownership, and civic contributions. Contrary to prediction, the scale did not relate to how long people had lived in their city. Explanations for this were offered and then conclusions were drawn about the potential usefulness of the scale.     

Birth Weight and Childhood Psychopathology in the ABCD Cohort: Association is Strongest for Attention Problems and is Moderated by Sex

Adolescents’ Behaviors as Moderators for the Link between Parental Self-Efficacy and Parenting Practices

Based on theory that parents with higher levels of self-efficacy (PSE) should find it easier to parent effectively in the face of challenging child behaviors than should parents with lower levels of PSE, this study examines the link between PSE and parenting using children’s behaviors as potential moderators. Participants were 130 parents who had an older adolescent (M _age?=?17.58) in addition to the target adolescent (M _age?=?11.79), and both adolescents’ externalizing behaviors were used as moderators for the link between PSE and parenting of the target adolescent. Path analysis in Mplus showed that higher PSE was linked to more promotive parenting but only among parents who had an older adolescent with lower levels of externalizing behaviors. Among parents of adolescents with higher levels of externalizing behaviors, whose promotive parenting was significantly lower than other parents overall, PSE did not predict promotive parenting. The link between PSE and parenting did not differ depending on the target adolescents’ behavior. Findings suggest that the link between parents’ beliefs and parenting depends on the broader family context. More specifically, how PSE is linked to parenting practices depends at least partly on the experiences that parents bring from parenting an older adolescent to their interactions with a later-born adolescent. From a clinical perspective, parents might need guidance in how to think about their earlier parenting experiences when parenting a younger adolescent.     

A Randomized Controlled Trial of the Say Yes to Life (SYTL) Positive Psychology Group Psychotherapy Program for Depression: An Interim Report

An RCT was conducted to evaluate the effectiveness of the Say Yes to Life (SYTL) positive psychology group psychotherapy program compared with treatment as usual (TAU). The current interim report is based on data from the first 82 cases recruited into the trial. There were 57 trial completers at post-treatment. At pretreatment on demographic and clinical variables, there were no significant differences between trial completers and dropouts in SYTL and TAU groups. There were two main significant (p < .01) findings. Compared with TAU treatment-completers, more than twice as many SYTL treatment-completers (28 vs. 72 %) were recovered 3 months after therapy using stringent recovery criteria (no longer meeting DSM-5 diagnostic criteria for major depressive disorder and scoring below clinical cut-off scores on the Beck Depression Inventory II, the Hamilton Rating Scale for Depression, and the Montgomery–Asberg Depression Rating Scale and showing reliable change on these three measures of depressive symptom severity). Second, the overall average service use cost per case in the SYTL group was significantly lower than that of the TAU group (€726 vs.€1187). This was largely due to the lower cost of the SYTL group therapy program compared with TAU which involved individual therapy. The pattern of results in an intention-to-treat analysis was similar to that in the completer analysis, though group difference did not reach significance due to inadequate statistical power and conservative missing data imputation procedures. It is planned to collect data on 100 trial completers, based on a power analysis.     

Innovative Retention Methods in Longitudinal Research: A Case Study of the Developmental Trends Study

Minimizing participant attrition is vital to the success of longitudinal research. The Developmental Trends Study (DTS), a longitudinal study of the development of disruptive behavior disorders, has achieved a low attrition rate throughout the study. The development of early retention strategies, managing contact and scheduling history through the use of electronic databases, interviewer persistence, and the emergence of new electronic search methods have contributed to the success of our study. A literature review of retention methodology and practical solutions to maintain participant cooperation is described. A case study of the DTS is presented to inform researchers in longitudinal research on new methods used to maintain high retention rates.
