The Marlowe-Crowne affair: short forms,psychometric structure,and social desirability

The Marlowe-Crowne Social Desirability scale (Crowne & Marlowe, 1960) is widely used to assess and control for response bias in self-report research. Several abbreviated versions of the Marlowe-Crowne scale have been proposed and adopted in psychology and medicine. In this article I evaluate the adequacy of 9 short forms using confirmatory factor analysis across 2 samples (combined N = 867). There was some evidence for the adequacy of different short forms, but model adequacy was not consistent across samples. Supplementary analyses revealed a multidimensional structure to the full Marlowe-Crowne scale and indicated that the apparent adequacy of model fit for some short forms might be a statistical artifact. Using the Marlowe-Crowne scale or its various short forms as a control for response bias is discouraged on empirical and conceptual grounds.     

A double dissociation of implicit and explicit memory in younger and older adults

This study examined whether age-related differences in cognition influence later memory for irrelevant, or distracting, information. In Experiments 1 and 2, older adults had greater implicit memory for irrelevant information than younger adults did. When explicit memory was assessed, however, the pattern of results reversed: Younger adults performed better than older adults on an explicit memory test for the previously irrelevant information, and older adults performed less well than they had on the implicit test. Experiment 3 investigated whether this differential pattern was attributable to an age-related decline in encoding resources, by reducing the encoding resources of younger adults with a secondary task; their performance perfectly simulated the pattern shown by the older adults in the first two experiments. Both older and younger adults may remember irrelevant information, but they remember it in different ways because of age-related changes in how information is processed at encoding and utilized at retrieval.     

Suicide After Evaluation for Involuntary Psychiatric Commitment—Who Gets Them and What Influences Survival Time?

Although involuntary psychiatric hospitalizations are associated with suicide risk, little is known about the relationship between evaluation for involuntary detention and suicide. We analyzed data on 10,082 suicides from 2000 to 2011 to examine demographics related to evaluation for detention and the association between demographics and evaluation dispositions on survival time. Evaluation preceded 11% of suicides; 53.8% of deaths occurred within 365 days, 6.5 times the expected rate. Males and older individuals were least likely to have been evaluated. Minority status and referral disposition influence 30‐day survival time. Risk is highly concentrated in the first year following evaluation.     

The effects of young children's affiliations with prosocial peers on subsequent emotionality in peer interactions

Preschoolers’ (60 boys and 64 girls, M age = 50.73 months) affiliations with prosocial peers were observed in naturally occurring interactions and then examined in relation to positive and negative emotionality within their peer interactions one semester later. Greater affiliation with prosocial peers in the fall was related to enhanced positive emotionality (especially for girls) and decreased negative emotionality (especially for boys) in later peer interactions. These findings held when initial levels of the emotion were controlled and were found above and beyond variations in classroom levels of prosociality. The findings suggest that peers exert influence in early childhood and that these effects can positively affect the quality of young children's later peer interactions.     

Music and Suicidality: A Quantitative Review and Extension

This article provides the first quantitative review of the literature on music and suicidality. Multivariate logistic regression techniques are applied to 90 findings from 21 studies. Investigations employing ecological data on suicide completions are 19.2 times more apt than other studies to report a link between music and suicide. More recent and studies with large samples are also more apt than their counterparts to report significant results. Further, none of the studies based on experimental research designs found a link between music and suicide ideation, prompting us to do a brief content analysis of 24 suicide songs versus 24 nonsuicide songs from the same album. Using Linguistic Inquiry and Word Count software, we found no difference in the content of the suicide songs and controls, including the percentage of sad words, negative affect, and mentions of death, thus providing an explanation for nonfindings from experimental research. In summary, ecologically based (which capture at‐risk persons not in typical school‐based samples) and more recent investigations (which have used superior or new methodologies) tend to demonstrate a linkage between music and suicidality. Experimental research is needed with a control group of songs from an alternative genre with low suicidogenic content.     

Obese, older adults with knee osteoarthritis: weight loss, exercise, and quality of life.

This study examined the effects of dietary weight loss and exercise on the health-related quality of life (HRQL) of overweight and obese, older adults with knee osteoarthritis. A total of 316 older men and women with documented evidence of knee osteoarthritis were randomly assigned to 1 of 4 18-month interventions: dietary weight loss, exercise, dietary weight loss and exercise, or healthy lifestyle control. Measures included the SF-36 Health Survey and satisfaction with body function and appearance. Results revealed that the combined diet and exercise intervention had the most consistent, positive effect on HRQL compared with the control group; however, findings were restricted to measures of physical health or psychological outcomes that are related to the physical self.
