Developmental stages: an integrating theory of group psychotherapy.

The inadequate nature of research into group psychotherapy stems from the lack of a satisfactory general theory that accounts for the group as a social system as well as for the functioning of the individual. A critique is presented of the group-as-whole tradition and a brief introduction given to social system concepts, particularly as they relate to group developmental stages. The idea that groups progress through a series of stages implies the notion of the group as a single entity with its own organizational structure. Specific stages are described through which the group acquires interactional complexity. These are conceptualized as epigenetic phenomena in that the mature structure is attained through an invariate sequence of transformations. Adequate resolution of any one stage is a prerequisite for further development. Group developmental tasks are described for the following stages: Engagement, Differentiation, Individuation, Intimacy, Mutuality and Termination. This set of higher order concepts has been found useful as a theoretical background against which specific group events can be evaluated. By using the idea of stages, the leader can monitor the progress of the group as a unit and compare the activity of any one member with the collectivity.

Psychological self-perception in male transsexuals, homosexuals, and heterosexuals.

Gender-related aspects of self-perception were explored for 24 anatomical males consisting of three matched groups of transsexuals, heterosexuals, and homosexuals. MacKenzie's Diagnostic Criteria Scale ratings were used to confirm group membership. Instruments used were the Repertory Grid Technique, the Rosenberg Self-Esteem Scale, Bem Self Role Inventory, Maferr Inventory of Masculine Values, and Derogatis Sexual Functioning Inventory. Results for transsexual subjects reflected lowest self-esteem. Of the three groups, they perceived themselves to be the most like females and the most unlike other males. Transsexual subjects tended to describe themselves in nonmasculine terms and valued their gender role orientation. Homosexual subjects, on the other hand, reported the highest self-esteem. Additionally, they saw themselves as the most similar to males and the most dissimilar to females. As a group, homosexual subjects described themselves in comparatively strong masculine-stereotyped fashion and valued this posture. However, they believed that women do not value the self-orientation which these subjects endorsed for themselves. Heterosexual subjects scored moderately high in terms of global self-esteem. They described themselves as somewhat masculine to androgynous and reported valuing their gender role orientation. Results on the Repertory Grid and the Derogatis Sexual Functioning Inventory showed heterosexual subjects to be the least polarized in their gender-related self-descriptions. This group generally appeared to be least concerned with traditional gender role referents. The importance of a cognitive approach to clinical assessment of the transsexual individual is stressed.

Evaluation of indomethacin by a controlled, cross-over technique in 30 patients with ankylosing spondylitis.

A clinical evaluation of indomethacin employing a controlled, cross-over technique with an inert placebo was undertaken in 30 patients with ankylosing spondylitis. Patients were studied for the frequency and dose relationship of side effects and for the subjective response of morning stiffness, chronic spinal pain, acute exacerbations of pain and peripheral arthralgia. Objective evaluation assessed measured change in movements of the cervical and lumbar spines, in chest expansion and in the range of movement of involved peripheral joints.Evaluation of the results indicated that a significant number of patients experienced side effects in the form of headache and dizziness while receiving indomethacin in doses above 150 mg. per day. Many other side effects reported by the patients were not found to occur at a statistically significant level. The significance of pulmonary infections encountered in three patients was reviewed. Relief of chronic spinal pain and peripheral arthralgia occurred in 14 and 16 patients, respectively (p < 0.05). Relief of morning stiffness and acute exacerbations of pain, and increase in the range of movement of any of the segments of the spine or the involved peripheral joints were not significant (p > 0.05). Based on the results of this study, it is suggested that the role of indomethacin in the management of ankylosing spondylitis be re-evaluated and that the daily therapeutic dose of this drug which has been heretofore recommended be decreased.
