Role of self-criticism in reward and punishment probabilistic learning

Reliability and Validity of the Self-Rating Scale as a Measure of Self-Criticism

The Self-Rating Scale (SRS; Hooley et al., 2010), a widely used measure of self-criticism in self-injury research, did not utilize conventional test development methods and has limited psychometric data. We examined the internal consistency, test-retest reliability, and convergent and discriminant validity of the SRS. Participants were 295 psychology undergraduate students. The SRS demonstrated good internal consistency (α = .93), adequate test-retest reliability (r = .76), and satisfactory convergent validity with other measures of self-criticism. Convergent validity was also adequate for expected dimensions of perfectionism (socially prescribed, self-oriented, concerns about mistakes, and doubts about actions), depressive symptoms, and negative and positive affect. The SRS demonstrated adequate discriminant validity with expected constructs of perfectionism (other-oriented, personal standards, and organizational perfectionism). Although the SRS appears to be a psychometrically sound measure of self-criticism, high correlations with depression and perfectionism raise questions regarding the overlap of these constructs.

The path from schizotypy to depression and aggression and the role of family stress

Background.

Schizotypy is a multidimensional construct that is linked to the vulnerability for psychosis. Positive schizotypy includes having paranormal beliefs. Negative schizotypy includes social anhedonia. Disorganized schizotypy includes social anxiety and communication disorder. Schizotypy relates to depression and aggression. Family stress from high expressed emotion (EE; a rating of criticism, hostility, and emotional overinvolvement in a close relative toward a person showing signs of mental disorder) may mediate the link between schizotypy, depression and aggression. This study tested, using path analyses, the hypotheses that schizotypy predicts depression and aggression through high perceived EE as criticism and irritability (hypothesis 1) and praise and intrusiveness in a close relative (hypothesis 2).

Methods.

One hundred and four healthy participants listened to and rated the self-relevance of standard criticism and standard praise that denote EE. Participants rated their level of schizotypy, depression, aggression, and perceived EE in self-report questionnaires. Two path models tested the hypotheses.

Results.

Disorganized schizotypy, more than positive schizotypy, predicted the path to depression and aggression when perceived criticism and perceived EE-irritability were mediators. Disorganised schizotypy, more than negative schizotypy, predicted the path to depression and aggression when perceived praise and perceived EE-intrusiveness were mediators.

Conclusions.

Greater perceived criticism and less perceived praise in family communication explain the path from disorganized schizotypy (more so than positive or negative schizotypy) to depression and aggression. These findings indicate a need to consider the thought disorder-EE link as a potential contributor to depression and aggression in people with schizophrenia.
