The stability of children's disorders was studied, using Adelaide versions of the Conners teachers and parent rating scales, with 5- to 12-year-olds. Of the 20 scales, 14 had high or moderate test-retest stability over the 1-year interval. Most scales also showed discriminant validity over this time. All but 2 of the 14 stable scales gave moderate stability coefficients at each of three age levels. Three teacher scales (Conduct Problem, Socially Rejected, and Antisocial) gave very low stability for the youngest group. Stability was not generally affected by teacher "practice." Little effect of subject selection or repeated-rating bias on scale means was evident. There was a general reduction of some scale means on the second assessment, and the contributions of practice, age, and study-entry effects were examined.

Matched groups of infertile and fertile married couples were studied by means of a psychiatric interview. The infertile wives exhibited significantly more hysterical and aggressive personality disorders and showed some evidence of ambivalence and difficulties concerning sexual relationships. The infertile patients in general did not exhibit significantly more neuroticism or psychoticism.

The EPI was administered to three student groups and to two clinical groups in studies allowing the investigation of Social Desirability(D) effects. Form A of the EPI and the Edwards D scale were completed by 100 students; Form A and the Crowne‐Marlowe D scale by 177 students; Form B and the Crowne‐Marlowe D scale by 175 students; and Form A, including the Lie (L) scale, by 38 potential renal transplant patients and 15 potential renal donors. Negative linear correlations between the Neuroticism (N) scale and the D or L scales were found for all groups. A very pronounced reduction in N scores was found with potential renal donors, together with high L scores. In most cases, no reliable correlation between Extraversion (E) and the D or L scales was found. The N and E scales were correlated negatively for Form B. Implications of these results for the use of the EPI are considered. Correlations with age and IQ were also obtained.

Previous research on attitude to authority has not adequately examined the generality of attitudes across different institutional authorities. This problem is distinct from "authoritarianism " and its purported concomitants. In this study, five scales were developed, relating to the Police, the Army, the Law, Teachers, and Symbolic Authority. The five scales showed a high degree of internal consistency on cross-validation. The intercorrelations among the scales, and with a Radicalism measure, demonstrated a high degree of generality in attitude towards institutional authorities. Moderate validity correlations were found with relevant reported activities: church attendance, participation in political demonstrations, and having been in conflict with teachers.
