The Struggle to Prevent and Evaluate: Application of Population Attributable Risk and Preventive Fraction to Suicide Prevention Researach

Population attributable risk (PAR) estimates have been used in suicide research to evaluate the impact of psychosocial and socioeconomic risk factors, including affective disorders, traumatic life events, and unemployment. A parallel concept of preventive fraction (PF), allowing for estimation of the impact of protective factors and effectiveness of preventive interventions, is practically unknown in suicidology. The study authors discuss the application of both concepts to suicide research and prevention, and review literature on the subject. Despite several methodological and conceptual limitations, both PAR and PF are valuable instruments to inform development and evaluation of suicide prevention programs.     

Who uses community mental health centres? A study of one health district

A caseload analysis was undertaken to investigate those clients seen by five community mental health centre teams within one healthcare district. The 985 clients are described in terms of demographic and clinical features and questions relating to service provision are discussed.     

The recognition of threatening facial stimuli

Two studies examined the information that defines a threatening facial display. The first study identified those facial characteristics that distinguish between representations of threatening and nonthreatening facial displays. Masks that presented either threatening or nonthreatening facial displays were obtained from a number of non-Western cultures and scored for the presence of those facial features that discriminated between such displays in the drawings of two American samples. Threatening masks contained a significantly higher number of these characteristics across all cultures examined. The second study determined whether the information provided by the facial display might be more primary nonrepresentational visual patterns than facial features with obvious denotative meaning (e.g., diagonal lines rather than downturned eyebrows). The subjective response to sets of diagonal, angular, and curvilinear visual stimuli revealed that the nonrepresentational features of angularity and diagonality in the visual stimulus appeared to have the ability to evoke the subjective responses that convey the meaning of threat.     

Recognition and recall of invisible objects

Three experiments examined recognition and recall of items that people imagined as being invisible. When one item hid another, the hidden item suffered in recognition, but so did the one that remained visible; the demand to imagine items invisibly made both items less recognizable than in control conditions. Cued recall did not depend on whether the visible item or the invisible item was the cue, but it did depend on whether the initial task required relational processing of the items. When both items were invisible in a dark imaginary scene, there was a general loss in all measures of memory, including memory for the scene. None of the results requires recourse to the “out of sight, out of mind” principle that memory depends on the visual characteristics of images. The results attest, instead, to the importance of the informational characteristics of memorial records.
