Achievement Motivation,Expected Coworker Performance,and Collective Task Motivation: Working Hard or Hardly Working?1

Social loafing is the tendency of individuals to work less hard collectively than individually. The present study examined the joint influence of achievement motivation and expected coworker effort on collective task performance. Participants (N= 107) who qualified and were available after pretesting on an achievement motivation scale were randomly assigned to a work condition and coworker effort condition. Dyads were asked to generate as many uses for a knife as possible within a 12‐min time period. Participants low in achievement motivation engaged in social loafing, but only when expected coworker effort was high, whereas participants high in achievement motivation did not engage in social loafing, regardless of expected coworker effort. The implication of achievement motivation for collective task performance settings is discussed.     

Young Adult Follow‐up of Adolescent Girls in Juvenile Justice Using the Columbia Suicide Severity Rating Scale

This study focused on the reliability and validity of the Columbia Suicide Severity Scale (C‐SSRS). Severely delinquent adolescent girls (n = 166) participated in a treatment trial and repeated assessments over time. Lifetime suicide attempt history was measured using the C‐SSRS in early adulthood (n = 144; 7–12 years postbaseline). Nonclinician raters showed strong interrater reliability using the C‐SSRS. Self‐reports, caseworker reports, and caregiver reports of girls' suicide attempt histories collected at baseline correlated with adult participants' recollections of their baseline attempt histories. Suicidal ideation measured prospectively across a 7‐ to –12‐year period was associated with retrospectively reported suicide attempt across the same period.     

Belongingness and Burdensomeness in Adolescents: Slovene Translation and Validation of the Interpersonal Needs Questionnaire

The Interpersonal Needs Questionnaire (INQ) for assessing thwarted belongingness (TB) and perceived burdensomeness (PB) has not been validated with community adolescents. We translated and administered the INQ to 307 Slovenian adolescents twice over 2–3 months and found that the 15‐item version (INQ‐15) did not fit without modification. TB and PB scales correlated with concurrent and later suicide ideation and lifetime suicide attempt history. The latent PB factor was associated with concurrent and later ideation controlling for TB, age, gender, depressive symptoms, binge drinking, and peer victimization. Suicide ideation and binge drinking were independently related to attempt history. Assessing and intervening on PB and binge drinking may be promising approaches to suicide prevention with community adolescents.
