The Basic Psychological Need Satisfaction and Frustration Scale: Some Satisfying and Frustrating Findings.

As a tool for operationalizing basic psychological needs theory (an aspect of self-determination theory), the Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS) has become the primary self-report measure. Here, with a sample of 807 Canadian military members, we confirm the BPNSFS six content factor structure and, in supporting that structure, demonstrate the differential association of satisfaction and frustration scales with psychological functioning variables that are external to the factor analysis. Although the specific content interpretation of the BPNSFS can be debated, we support the continued use of the BPNSFS as a psychometrically sound instrument.

Psychopathic Traits and the Cheater-Hawk Hypothesis.

The present study was a direct test of the cheater-hawk hypothesis which argues that psychopathy is related to two potentially adaptive interpersonal strategies: cheating and aggression. As expected, the measures of cheater and hawk behaviors comprised a single factor, according to a maximum-likelihood factor analysis. As hypothesized, psychopathic traits exhibited large positive correlations with measures of both cheater (entitlement, exploitiveness, and short-term mating orientation) and hawk (vengeance and aggression) behaviors.
