Sexual development, age, and dating: a comparison of biological and social influences upon one set of behaviors.

Data from the U.S. National Health Examination Survey of 12-17-year-old youths were used to determine whether the development of the social behavior of dating is more closely linked to the level of sexual maturation or to the progression through age grades without reference to sexual maturation. Regression analyses and partial correlations show that individuals levels of sexual maturation add very little to the explained variance in dating after age had been taken into account. It appears that social pressures, based on behavior considered typical and appropriate at various ages, determines the onset of dating in adolescents. Individual rates of sexual maturation that deviate from the norm for that age have little impact on dating. These findings show how social standards can reduce dramatically the impact of individual biological processes on institutionalized forms of behavior.

Adolescents' self-assessment of sexual maturation.

The variability in time on onset and progression of puberty warrants the use of stage of sexual maturation rather than chronologic age in assessing biological and behavioral measures during adolescence. The necessity to undress the teenage has seriously curtailed the application of stage of sexual maturation to behavioral and developmental research. This study demonstrated that adolescents can accurately assess their own developmental stage according to Tanner's standard photographs. Self-ratings by 43 females, aged 9 to 17, and 23 males, 11 to 18, were compared to those based on physical examination by one of the investigators. Agreement with the physician rating occurred for breast stage in 37/43, for female pubic hair stage in 40/43, and for male combined pubic hair and genital stage in 21/23 (kappa coefficients: 0.81, 0.91, 0.88). The excellent agreement between physician and adolescent's assessment compared favorably with the interrater agreement of professionals. This study suggests the value of utilizing adolescent self-staging in research. In addition, this exercise provides teenagers with an objective way to understand the wide range of normal pubertal development and to follow their own sexual maturation.

The assessment of anxiety and fear in persons with chronic pain: a comparison of instruments.

Instruments used to study anxiety and fear responses related to chronic pain vary along two dimensions. They differ in terms of the stimuli or situations that evoke anxiety responses and the types of anxiety responses included (i.e. cognitive, motoric, and physiological). This study examined relations of variables from the Pain Anxiety Symptoms Scale (PASS), the Fear-Avoidance Beliefs Questionnaire (FABQ), the Fear of Pain Questionnaire (FPQ), and the trait version of the Spielberger State-Trait Anxiety Inventory (STAI) with variables related to pain severity, perceived disability, and pain behavior. Subjects were 45 consecutive referrals to a university pain clinic who completed these measures during their evaluation. Results suggested that anxiety responses directly related to the patient's particular pain sensations are more relevant to the understanding of chronic pain than are more general tendencies to respond anxiously or fear more varied pain stimuli. Regression analyses showed that empirically selected subsets of the anxiety variables predict from 16 to 54% of the variance in pain severity, disability and pain behavior. Also, assessment of multiple anxiety response types appears useful for understanding pain behavior and disability. Further study of fear and anxiety responses of persons with pain is likely to benefit from careful selection of measures dependent on the stimulus and response dimensions assessed.
