Hospital-Treated Psychiatric Disorders in Adults with a Single-Parent and Two-Parent Family Background: A 28-Year Follow-up of the 1966 Northern Finland Birth Cohort

This study investigates the relationship between the family type (two-parent and 4 different single-parent types, mainly divorced) during childhood up to 14 years of age and adult hospital-treated psychiatric disorders in a sample from the unselected, general population Northern Finland 1966 Birth Cohort (N = 11,017). Up to the end of 1994, a total of 387 individuals (3.5%) had a hospital-treated psychiatric disorder, with 3.1% in two-parent families and 5.4% in single-parent families (p < .001). The single-parent family was not associated with the child's schizophrenia or other psychotic disorders. The adjusted odds ratios (OR) for personality disorders were highest among individuals without a father before the age of 14 years (OR 4.8), or at birth only (OR 4.0), or with a history of parental divorce (OR 2.8). Parental divorce was also associated with alcoholism (OR 3.7) and parental death with depressive disorders (OR 3.4). In conclusion, we found an elevated risk of hospital-treated nonpsychotic disorder among individuals from a single-parent family background. It is likely that a combination of the single-parent family and psychosocial and/or genetic risk may influence the development of these disorders.     

Personality profiles and health: Longitudinal evidence among Finnish adults

Kinnunen, M.‐L., Metsäpelto, R. L., Feldt, T., Kokko, K., Tolvanen, A., Kinnunen, U., Leppänen, E. & Pulkkinen, L. (2012). Personality profiles and health: Longitudinal evidence among Finnish adults. Scandinavian Journal of Psychology 53, 512–522. This study investigates the associations of longitudinal Big Five personality profiles with long‐term health in 304 adults (53% males). Personality traits (Neuroticism, Extraversion, Openness, Conscientiousness, Agreeableness) were assessed at ages 33, 42, and 50. Subjective (self‐rated health, symptoms, psychological distress) and objective (body mass index, waist‐to‐hip ratio, blood pressure, cholesterol, triglycerides) indicators of health were measured at ages 42 and 50. Five longitudinally stable personality profiles were extracted over 17 years by latent profile analysis. The levels of traits were the same in each profile at each age. Resilient individuals (N = 65; Neuroticism low, other traits high) had the best subjective health and Overcontrolled individuals (N = 40; Neuroticism high, other traits low) the poorest health over eight years. Reserved individuals (N = 25; high Conscientiousness, other traits low), Undercontrolled (N = 41; high Openness and Extraversion, low Conscientiousness), and Ordinary (N = 133; all traits scored medium) individuals were in the middle of these extremes in subjective health. No differences between the profiles were found in the objective indicators of health. Thus, overcontrol and resilience were most discriminative in terms of good health. Moreover, personality profiles revealed associations with health to be more nuanced than simply being composed of single traits. High Extraversion needed to be combined with high Conscientiousness (Resilients) in order to be associated with the best health; high Extraversion with low Conscientiousness (Undercontrolled) was associated with average health; and low Extraversion with high Neuroticism (Overcontrolled) was associated with the poorest health.     

The Attention and Executive Function Rating Inventory (ATTEX): Psychometric properties and clinical utility in diagnosing ADHD subtypes

Klenberg, L., Jämsä, S., Häyrinen, T., Lahti‐Nuuttila, P. & Korkman, M. (2010). The Attention and Executive Function Rating Inventory (ATTEX): Psychometric properties and clinical utility in diagnosing ADHD subtypes. Scandinavian Journal of Psychology, 51, 439–448. This study presents a new inventory, the Attention and Executive Function Rating Inventory (ATTEX), and examines the psychometric properties and the clinical utility of ATTEX in indentifying the attention deficit hyperactivity disorder combined type (ADHD‐C) and the ADHD predominantly inattentive type (ADHD‐I) in school environments. A normative sample of Finnish 7‐ to 15‐year‐old children and adolescents (N = 701) and a clinical sample consisting of children with ADHD‐C (N = 190) and ADHD‐I (N = 25) were examined with the ATTEX and the ADHD Rating Scale‐IV. The ATTEX and its scales had good internal consistency reliability (0.67–0.98) and criterion validity (0.68–0.95). Normative data was provided for the total normative sample and for boys and girls separately. Gender differences were noted in the ATTEX scores, boys having consistently higher scores on all ATTEX scales. The effect of age was significant only for one of the ten scales, the Motor hyperactivity scale, 7‐year‐olds having more problems of hyperactivity than 14‐year‐olds. Lower parent education level and the child’s learning difficulties were related to higher ratings of EF problems in ATTEX. When different cutoff scores for boys and girls were applied, ATTEX was sensitive in identifying children with attention deficit disorders. In addition, ATTEX was accurate in differentiating children with ADHD‐I from children with ADHD‐C. In this Finnish sample, ATTEX showed solid psychometric properties and could be used as a reliable tool in the diagnostic evaluation of ADHD‐C and ADHD‐I.
