Abstract

Background and aims:

Several instruments have been developed to detect subjects who are at risk for mental disorders.

Aims:

We aimed to address the predictive validity of several personality, schizotypal and mania scales for psychiatric hospitalisations.

Methods:

As part of the 31-year follow-up survey of the Northern Finland 1966 Birth Cohort, Temperament and Character Inventory (TCI, temperament part), Physical Anhedonia Scale, Social Anhedonia Scale (SAS), Perceptual Aberration Scale, Hypomanic Personality Scale (HPS), Bipolar II scale (BIP2) and Schizoidia scale were filled in by 4,857 subjects. We dichotomized scores in the scales (highest 10% by gender vs. others). Also subscales of TCI and BIP2 were used as predictors. In a longitudinal study setting using hospital discharge register we followed those without previous hospitalisation (N=4,727; 2,092 males and 2,635 females) from 31 years for eight years and recorded hospitalisations due to psychotic, substance use, anxiety, mood and personality disorders.

Results:

In total 78 (1.7%) of subjects were hospitalized due to psychiatric disorder during the follow-up. Most of the instruments predicted several disorders. Mood lability subscale of BIP2 predicted (p<0.05) all diagnostic groups. Most specific predictors were SAS (Odds Ratio 3.84; 95% CI 1.44-10.28) and HPS (4.01; 1.52-10.60) for psychosis and novelty seeking subscale of TCI (3.00; 1.41-6.36) and energy/activity (2.68; 1.26-5.68) and social anxiety (3.90; 1.84-8.28) subscales of BIP2 for substance use disorders.

Conclusions:

Scales measuring schizotypal or manic symptoms were good predictors for different psychiatric hospitalisations. Many of the scales predicted several disorders, only few scales predicted only one specific disorder.
