Comparison of reactive and non-reactive measures of smoking cessation at follow-up.

Subjects who had completed a smoking cessation program were contacted at 3- and 4-month follow-up to assess self-reported frequency of daily cigarette smoking. Subjects were randomly assigned to a reactive or non-reactive condition of telephone contact in obtaining the self-report. In the reactive condition, the telephone caller seeking self-report identified herself as an assistant in the original smoking cessation treatment program. In the non-reactive condition the telephone caller identified herself as an employee of a firm conducting a market research survey of the use of various consumer products. There were no statistically significant differences between the conditions in either self-report of abstinence or absolute frequency of daily cigarette consumption.

Effects of biochemical validation of self-reported cigarette smoking on treatment success and on misreporting abstinence.

Many investigators have reported that cigarette smokers who are trying to quit often falsely report being abstinent at the end of treatment. Unfortunately, much of the previous research designed to investigate this problem has been flawed, making the results difficult to interpret. We attempted to avoid these flaws and to investigate the measurement of alveolar carbon monoxide (CO) levels to validate self-reported smoking rates at the end of treatment. Participants in behavioral cessation clinics were randomly assigned to one of three conditions that varied in timing of exposure to information regarding CO measurement: at the beginning of treatment (demonstration of CO measurement, discussion of smoking effects on CO levels, and notification that individual CO levels would be measured at the conclusion of the clinic), at the end of treatment (demonstration, discussion, and notification of CO measurement prior to self-reports of smoking levels), or at the end of treatment (demonstration and discussion of CO measurement subsequent to self-reports of smoking levels). CO levels of all participants were measured at the end of treatment after they reported their current smoking levels. Only 16% of self-reports of abstinence were not verified by CO measurement. Smokers who observed the CO demonstration at the beginning of treatment were significantly more likely than the other two groups to achieve abstinence at the end of treatment and significantly less likely to misreport abstinence. Clinical and research implications of these results are discussed.

The validity of self-reported drug use in non-treatment seeking individuals with cocaine dependence: correlation with biochemical assays.

Accurate estimate of drug exposure plays an important role in studies of the neurobiology of drug dependence. The validity of self-reported drug use by subjects participating in such studies has not been well established. This study examined the relationship between self-reported drug use and biological markers in 18 non-treatment-seeking cocaine-dependent individuals participating in research on the effects of cocaine on the brain. A significant relationship was found between self-reported frequency of cocaine use and hair cocaine concentration. Frequency of alcohol use correlated significantly with plasma carbohydrate-deficient transferrin and aspartate aminotransferase levels. These results suggest that self-reported substance use in non-treatment seeking research subjects is generally valid.

Construct validity of the misrepresentation scales of the psychological screening inventory.

This study provides construct validity evidence and reliabilities (consistency and stability) for 5 misrepresentation (response distortion) scales of the Psychological Screening Inventory (PSI; Lanyon, 1970, 1973, 1978) in assessing 3 constructs: exaggeration of psychopathology, exaggeration of personal virtue, and exaggeration of health problems. Using data from forensic cases, the existence and independence of these 3 constructs were confirmed in data from the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and the Balanced Inventory of Desirable Responding (Paulhus, 1986, 1991). The PSI scales were then shown to load highly on these constructs. The PSI scales also showed the expected patterns when their mean scores were examined for 15 sets of responses from participant groups with varied motivations to misrepresent. We present receiver operating characteristic data to show the success of the scales in distinguishing between simulators and appropriate comparison groups. Using the same data, we also present classification accuracy in terms of positive predictive power and negative predictive power based on a sensitivity level of 90% and misrepresentation base rates of .20 and .10.

Social reactions to child sexual abuse disclosures: a critical review.

Recent studies have examined disclosure of child sexual abuse to determine the correlates and consequences of telling others about this form of victimization. The present article reviews the current empirical literature on disclosure and reactions to adult survivors to assess what is known about the process of disclosure and whether telling others is therapeutic and leads to positive outcomes. Most studies assessing social reactions in detail have concerned adult survivors retrospectively reporting on their disclosures of child sexual abuse. Few empirical studies have been conducted in this area but research suggests that few victims tell anyone about child sexual abuse as children, and that the type of reactions to disclosure vary according to when disclosure occurs (childhood or adulthood), the extent and nature of the disclosure, and the person to whom one discloses. Clear evidence shows that negative social reactions are harmful to survivors' well-being, but better assessment of specific reactions and their effects are needed in theoretically-based studies to evaluate how these responses affect survivors' recovery in the context of other variables. Suggestions for future research on social reactions of others to adult survivors disclosing child sexual abuse are presented.

The role of disclosing child sexual abuse on adolescent adjustment and revictimization.

The role of disclosing child sexual abuse on adolescent survivors' symptomatology and the presence of additional unwanted sexual experiences was investigated in a subsample of 111 adolescents from the National Survey of Adolescents who reported child sexual abuse. Results indicated that prompt disclosure of sexual abuse to an adult moderated the influence of penetration during the abuse on the number of symptoms at assessment. Thus, prompt disclosure buffered the influence of more severe abuse. Disclosure also had a main effect on the likelihood of further victimization. Participants who told an adult promptly after the abuse were less likely to report additional unwanted sexual experiences.

Pattern reliability of narcotics addicts' self-reported data: a confirmatory assessment of construct validity and consistency.

Pattern reliability, or the invariance of relationships among variables, was investigated in this study. The consistency of theoretical constructs reflected by measures taken at two separate occasions can be tested using confirmatory factor analysis. Self-report data were obtained from 323 narcotics addicts in two face-to-face interviews conducted in 1974/75 and 1985/86. The two interviews overlapped approximately 4 years between 1970 and 1974/75. Through the testing of the invariance of measurement and structural models, pattern reliability was confirmed in one of the models developed. Explication of pattern reliability offers an alternative means of assessing validity of self-report data.

Questioning diagnosis disclosure in terminal cancer patients: a prospective study evaluating patients' responses.

This study attempted to assess the degree of knowledge of the diagnosis, and the attitude towards that information, in a group of terminally ill cancer patients. We also tried to determine the influence of the knowledge of the diagnosis on other patient psychosocial needs. We assessed 97 patients (64 in an oncology service, 33 in a palliative care unit) by means of a semistructured personal interview, and a psychosocial needs questionnaire. Data collected showed that 68% of patients had not been informed of their diagnosis; 60% of this group had a high degree of suspicion of their diagnosis, but 42% of noninformed patients did not want to receive more information. Information on diagnosis appears to be beneficial in establishing satisfactory relationships and communication between patients and relatives and staff. We have tried to answer the most relevant issues related to diagnosis disclosure in our clinical setting, questioning the feasibility of truth telling within our cultural boundaries.
