Psychological functioning and family discord among African-American adolescent females with and without a history of childhood sexual abuse.

OBJECTIVES: The aim was to examine the rate of childhood sexual abuse along with the factors (age of abuse onset, type of perpetrator, and duration of the abuse), as well as the relationship of these factors to psychological functioning among females with a history of childhood abuse. Second, to determine whether levels of psychological functioning and family discord differ among females with and without a history of childhood sexual abuse. METHOD: A cross-sectional design was used. Two hundred and forty-nine adolescent females were recruited from a community-based health program. Two trained female interviewers administered an anonymous survey that assessed childhood sexual abuse, psychological functioning, and family environment. RESULTS: Fifty-seven (22.9%) of those surveyed reported childhood sexual abuse, of which 44.3% were intrafamilial and 55.7% were interfamilial. Age at onset ranged from 3 years to 17 years; 62.5% reported that the sexual abuse occurred 1 to 4 times; 27.9% reported a duration ranging from 1 year to 13 years; and 9.6% reported a duration of 1 month to 7 months. Multiple regression analysis revealed that a greater duration predicted higher levels of depression and lower levels of self-esteem among females with a history of sexual abuse. Females with a history of childhood sexual abuse scored significantly lower on measures of self-esteem and mastery, and significantly higher on measures of physical and emotional abuse. CONCLUSIONS: Results indicate that adolescent females with a history of childhood sexual abuse suffer an array of negative sequelae that include psychological and family distress.

Reliability and validity of a self-efficacy instrument specific to sickle cell disease.

The psychometric properties of a new, 9-item scale measuring disease-specific perceptions of self-efficacy were investigated in a community-based sample of adults (N = 83) with sickle cell disease (SCD). The Sickle Cell Self-Efficacy Scale (SCSES) was comprised of nine questions relating to participants' perceptions of their ability to function on a day-to-day basis and to manage SCD symptomatology (e.g. episodes of pain). The SCSES demonstrated good internal consistency, discriminant validity, and convergent and predictive validity, both with previously validated measures of related constructs as well as with reported SCD symptomatology. Overall, the instrument appears to be reliable and valid for assessing clients' self-efficacy for engaging successfully in day-to-day activities despite having SCD. Future investigators may wish to examine temporal and causal links between alterations in self-efficacy and changes in adjustment to sickle cell disease; the SCSES provides a psychometrically sound tool with which to investigate these phenomena.

Hispanic adults' beliefs, attitudes, and intentions regarding the female condom.

The present study used the theory of planned behavior (TPB) (Ajzen, 1985) augmented by AIDS knowledge to investigate factors influencing intentions of Hispanic adults to use the female condom. A total of 146 persons (75 women and 71 men; mean age, 27 years) recruited from community-based organizations completed an anonymous survey regarding intentions to use the female condom with their main sex partner. The TPB model had greater predictive utility for women's, than for men's, female condom use intentions. For men, attitudes and norms did not predict female condom use intentions, but greater AIDS knowledge was related to lower intentions to use the female condom, above and beyond the TPB constructs. Perceived behavioral control, operationalized as self-efficacy, significantly increased the predictive utility of the TPB model for women's female condom use intentions but not for men's. Behavior change strategies to increase female condom use are discussed in light of these findings.

Meanings assigned by undergraduates to frequency statements of condom use.

Studies of condom use must rely upon self-report data which may not be reliable and valid. This investigation examined how 192 undergraduates (17-48 years) interpret response categories (never, rarely, sometimes, most of the time, always) used in some surveys to assess frequency of condom use. Subjects completed a questionnaire that described a scenario of a couple who had engaged in sexual intercourse 20 times during the past 3 months. As part of the survey, there were 21 statements in which the stated number of times condoms were used varied from 0 to 20 (e.g., condoms were used 18 out of the 20 episodes of sexual intercourse). For each statement, subjects were instructed to circle the category they believed best matched the frequency with which condoms had been used: 31% indicated that using condoms 1 out of 20 times was an example of never using condoms; similarly, 23% indicated that using condoms 2 times out of the 20 encounters was an example of never using condoms, 40% indicated that condom use for 19 out of 20 encounters was always using condoms, whereas 23% applied the always label to condom use for 18 out of 20 encounters. These results generally support the validity of this type of condom use measurement, but suggest that caution is needed in interpretation. Implications of these findings are discussed with respect to health messages and research methodology.

Reliability and validity of a self-efficacy instrument for protective sexual behaviors.

The authors investigated the psychometric properties of a 22-item scale that measured respondents' perceptions of their ability to refuse sexual intercourse, question potential sexual partners, and use condoms. Two hundred twenty-one male and female undergraduates completed an anonymous questionnaire that measured a wide range of constructs. The scale exhibited good internal consistency, and convergent validity was demonstrated for 5 sexual behavior items (number of sexual partners ever and in the past 3 months, condom use in past 3 months, at last intercourse, and in the future). The instrument appeared to be free of social desirability bias and was reliable and valid for assessing college students' self-efficacy for protective sexual behaviors. College healthcare professionals could administer the instrument to help students determine their levels of self-efficacy for engaging in self-protective behaviors and identify domains in which they may need to improve their skills to reduce their risks of acquiring a sexually transmitted disease or having or causing an unplanned pregnancy.

Psychometric properties of the MSPSS and NOS in psychiatric outpatients.

Prior research has demonstrated the utility of the Multidimensional Scale of Perceived Social Support (MSPSS) and the Network Orientation Scale (NOS) as measures of perceived social support among nonpsychiatric samples. The primary objective of this study was to determine whether these two scales can be used reliably among psychiatric outpatients, in particular those with schizophrenia or a major affective disorder. Subjects were 144 outpatients, aged 21 to 67 years, who completed the MSPSS and NOS. Results demonstrated high internal consistency for the MSPSS and adequate internal consistency for the NOS. In addition, convergent validity was demonstrated. Scores on both scales for these psychiatric outpatients were found to be lower as compared to "normals."

Norplant removal facilitated by use of ultrasound for localization.

Two case reports are presented, describing the use of a 7-MHz ultrasound transducer to locate and visualize Norplant rods that could not easily be removed. The first patient was referred to the radiology department for a sonogram for unrelated reasons; her self-reported history led to the attempt to locate a retained Norplant rod. The second patient was first referred by a physician for the stated purpose of rod localization. After ultrasonic localization of the retained rods, both patients returned to their physicians' offices and underwent successful removal of the rods. Morbidity related to difficult rod retrieval can be reduced by using ultrasound for localization.

Effect of modifications of semen diluent with cell culture serum replacements on fresh and stored turkey semen quality and hen fertility.

Two commercially available serum replacements formulated as supplements to somatic cell culture media were used with a turkey semen diluent to determine their effect on semen quality and spermatozoal fecundity before and after semen storage for 24 h. Progressive motility estimates (visual) and spermatozoal motility characteristics estimated by a computer-assisted semen analysis system, and sperm viability tests (the ethidium bromide exclusion procedure and a sperm stress test) were used to evaluate the semen. Although the presence of the serum replacements significantly increased spermatozoal motility, fertility was not augmented by the presence of the serum replacements. Computer-derived spermatozoal velocity and the percentage of nonviable spermatozoa estimated by the sperm stress test were negatively correlated with hen fertility. It was concluded that although the serum replacements augmented some spermatozoal motility characteristics, they failed to improve the fecundity of spermatozoa either before or after semen storage for 24 h.

Self-efficacy as a predictor of adult adjustment to sickle cell disease: one-year outcomes.

OBJECTIVE: The present study prospectively investigated the role of self-efficacy in predicting disease symptomatology and health services utilization for adult patients with sickle cell disease. METHODS: These data are derived from a 12-month prospective cohort study of African American adults with sickle cell disease. Disease-specific perceptions of coping self-efficacy and indices of disease severity, health care utilization, and psychosocial adjustment were assessed by use of standardized questionnaires administered by trained clinicians. RESULTS: Perceptions of self-efficacy for coping with sickle cell disease were moderately stable across the 12-month study period. At baseline (N = 147), significant inverse relationships, measured with Pearson correlations, were noted between self-efficacy and the following variables: physical symptoms, psychological symptoms, pain severity, and number of physician visits over the preceding 12 months (p <.01). Similar relationships with self-efficacy were noted at the 1-year follow-up (N = 104) period for measures of physical symptoms, psychological symptoms, and pain severity (p <.01). In multiple-regression models, baseline self-efficacy scores predicted changes over the 1-year study period in physical and psychological sickle cell disease symptomatology. Moreover, changes in self-efficacy from baseline to 1-year follow-up were significantly and independently related to changes in physical symptoms, psychological symptoms, and pain ratings from baseline to 1-year follow-up. CONCLUSIONS: Self-efficacy beliefs among African American adults with sickle cell disease are inversely related to reported disease symptomatology, and these relationships persist across time. Future investigations should examine the mechanisms through which relationships between self-efficacy and adjustment to sickle cell disease are effected, as well as the feasibility and effectiveness of enhancing self-efficacy beliefs as a means of improving adjustment to sickle cell disease.
