Modelling decisions to undergo genetic testing for susceptibility to common health conditions: An ancillary study of the Multiplex Initiative

New genetic tests reveal risks for multiple conditions simultaneously, although little is understood about the psychological factors that affect testing uptake. We assessed a conceptual model called the multiplex genetic testing model (MGTM) using structural equation modelling. The MGTM delineates worry, perceived severity, perceived risk, response efficacy and attitudes towards testing as predictors of intentions and behaviour. Participants were 270 healthy insured adults aged 25–40 from the Multiplex Initiative conducted within a health care system in Detroit, MI, USA. Participants were offered a genetic test that assessed risk for eight common health conditions. Confirmatory factor analysis revealed that worry, perceived risk and severity clustered into two disease domains: cancer or metabolic conditions. Only perceived severity of metabolic conditions was correlated with general response efficacy (β?=?0.13, p<0.05), which predicted general attitudes towards testing (β?=?0.24, p<0.01). Consistent with our hypothesised model, attitudes towards testing were the strongest predictors of intentions to undergo testing (β?=?0.49, p<0.01), which in turn predicted testing uptake (OR 17.7, β?=?0.97, p<0.01). The MGTM explained a striking 48% of the variance in intentions and 94% of the variation in uptake. These findings support use of the MGTM to explain psychological predictors of testing for multiple health conditions.     

Caregivers’ beliefs about dementia: findings from the IDEAL study

Abstract

Objective: Informal caregivers of people with dementia develop their own beliefs about the condition, referred to as Dementia Representations (DRs), as they try to make sense of the changes they are observing. The first aim of this study was to provide a profile of the types of DRs held by caregivers. The second aim was to examine the impact of caregivers’ DRs on their well-being, satisfaction with life (SwL) and caregiving stress.

Methods: Participants were 1264 informal caregivers of people in the mild-to-moderate stages of dementia from time-point 1 of the IDEAL cohort study.

Measures: DRs were measured using questionnaire items covering: Identity, Cause, Control, and Timeline.

Results: Almost half (49.2%) of caregivers used a diagnostic term to describe the person’s condition, although 93.4% of caregivers stated they were aware of the diagnosis. Higher well-being, SwL, and lower caregiving stress were associated with the use of an identity term relating to specific symptoms of dementia, attributing the cause to ageing or not knowing the cause, and believing the condition would stay the same. Lower well-being, SwL, and higher caregiving stress were associated with believing there was little that could be done to control the effects of the condition.

Conclusion: Healthcare professionals should assess and gain an understanding of caregivers’ DRs in order to provide more tailored information and support.     

The Influence of Differing the Paths to an Incentive on Third Graders’ Reading Achievement and Attitudes

The purpose of this study was to examine the impact of four incentive paths on third graders’ reading vocabulary and comprehension achievement and recreational and academic reading attitude. One hundred and twenty third-grade students were assigned to one of four incentive path treatment conditions. Data were analyzed using analysis of covariance (ANCOVA) with Fisher's least significant difference (LSD) post hoc comparisons. An effect size of .09 was calculated using a partial η² (eta squared) statistic. Findings indicated that the four incentive path treatment conditions did not differentially impact student vocabulary, comprehension, and recreational reading. A significant difference for students’ academic reading attitudes was identified across the four incentive path treatment conditions.     

Illicit Sexual Behavior: A Test of Self-Control Theory

Gottfredson and Hirschi (1990 Gottfredson , Michael and Travis Hirschi . 1990 . A General Theory of Crime . Standford , CA : Standford University Press . [Google Scholar]) contend that all deviance is subsumed under self-control theory and that individuals who commit any one deviant act will tend to commit other deviant acts as well. This research tests the correlation of illicit sexual behaviors with crime as they relate to measures of self-control. Secondly, this research examines the Gottfredson and Hirschi argument that their theory is a “general theory” and predicts all forms of deviance whereby low self-control is a predictor of both sexual deviance and crime. These analyses report illicit sexual behaviors are positively correlated with criminal behaviors providing support for Self-Control Theory. Furthermore, the analyses of this data support that low self-control is a predictor of illicit sexual behaviors and crime.     

The Effect of an Occupational Therapy Role-Playing Intervention on the Social Skills of Adolescents With Asperger's Syndrome: A Pilot Study

The purpose of the authors in this pilot study was to assess the effects of an occupational therapy role-playing intervention for adolescents with Asperger's syndrome. An ABA multiple baseline single-subject design across participants was used with three adolescents to determine if a six-week intervention could increase targeted social behaviors. Data were collected over baseline, intervention, and probe phases. Three methods of analysis were used: visual inspection of graphed data, paired t tests, and a three standard deviation-band approach. Findings demonstrated that all three participants were able to increase the frequency of targeted social skill use from baseline to intervention and maintain this level at a one month probe. Differences between baseline and intervention phases for each participant reached statistical significance. Through this study the authors offer preliminary evidence that an occupational therapy role-playing intervention that is both client centered and graded can increase targeted social skill use in three adolescents with Asperger's syndrome.     

Qualitative Methods in Family Evaluation: Creative Assessment Techniques

Traditionally, family therapists have used experiential activities primarily as interventions. In this article, the authors discuss the role that experiential therapy methods can play in qualitative family assessment. It is believed that these methods can be quite helpful in engaging family members in a collaborative evaluation process. The authors discuss the advantages of qualitative assessment as complement to more quantitative family evaluation measures and present several illustrative qualitative assessment procedures.     

Family Mealtimes and Family Functioning

ABSTRACT

This study contributes to the existing research literature by assessing how the frequency of family mealtimes correlates with family communication and life satisfaction. Participants consisted of 50 families from the Southeastern United States. Parent and child participants completed measures assessing frequency of family mealtime, family communication, and family satisfaction. Results indicated that, based on parent-report, the frequency of all family members eating dinner together was significantly and positively correlated with both family communication and family satisfaction. Implications of findings highlight the importance of encouraging regular mealtime interactions among families.     

Attitude and knowledge changes in collegiate dancers following a short-term, team-centered prevention program on eating disorders

Eating knowledge, nutritional knowledge, and psychological changes among female collegiate dancers were examined before and after a 4-wk. team-centered program on sport nutrition, exercise, and disordered eating consequences. Collegiate female dancers from two NCAA Division I institutions participated in a control (n = 19; M age = 19.1 yr., SD = 1.0) or intervention (n = 21; M age = 19.2 yr., SD = 1.2) group. Measures were administered to both groups before and after intervention to assess eating disorders, depression, and nutritional and disordered eating knowledge. There was a statistically significant increase in scores on nutritional and overall eating disorder knowledge in the intervention group compared to the control group. Mean scores on depression, drive for thinness, body dissatisfaction, and maturity fears decreased in the intervention group.     

Opportunistic propensity hinders commitment to acts in conditions of forced compliance and compliance without pressure

The psychosocial literature contains empirical evidence of the effects of personality variables on commitment to acts. The association of economic opportunism was explored with respect to postexperimental attitude change, intentions, and intrinsic motivation of individuals (N=132) toward acts with either forced compliance or compliance without pressure. In conditions of commitment and compliance without pressure, both intention and intrinsic motivation decreased as economic opportunism increased, while in conditions of commitment and forced compliance, intention increased as economic opportunism increased. Attitude change and economic opportunism did not appear to be associated in any experimental condition. These findings suggest that tendency to noncooperativeness predisposes to reduced concern for consistency and compliance with performed acts.     

Distinguishing among nondirect forms of aggression

This study explored the relationships and differences among two measures of indirect aggression [Bjorkqvist et al., 1994; Richardson and Green, 1997] and one of relational aggression [Crick and Grotpeter, 1995]. Over 300 students (mean age 22.8 years; 61.5% female) from two colleges in the Southeastern United States completed measures of indirect and relational aggression and related constructs (e.g., empathy, anger expression, direct aggression). Although there were subtle differences among the three measures with regard to their relationships with associated variables, overall the patterns of relationships were similar as well as distinct from the pattern for direct aggression. Factor analysis of scores for measures of aggression revealed that the indirect and relational measures composed a single factor of nondirect aggression, separate from direct aggression. Further factor analysis of all unique items from the nondirect scales found the overall construct of nondirect aggression to comprise six distinct factors. Implications for applications and further research are discussed.
