Cognition checklist for mania-revised.

The Cognitive Checklist for Mania-Revised (CCL-M-R), which measures the severity of maladaptive beliefs and cognitions associated with mania, was administered to 35 inpatients with a major depressive disorder, 20 inpatients with a schizoaffective disorder, and 45 inpatients with a bipolar I disorder to determine whether cognitions associated with mania differentiate patients who have most recently experienced either manic, mixed, or depressive episodes. The CCL-M-R is composed of four subscales assessing (a) exaggerated beliefs about self-worth (Myself), (b) grandiose beliefs about interpersonal relationships (Relationships), (c) erroneous beliefs about needing excitement from engaging in high risk situations (Pleasure/Excitement), and (d) unrealistic beliefs about having high energy levels for undertaking goal-driven activities (Activity). As hypothesized, the mean CCL-M-R total, Myself, Relationships, and Activity scores of the 26 patients with manic episodes were higher than those for either the 17 patients with mixed episodes or the 57 with depressive episodes. The CCL-M-R was discussed as a reliable and valid instrument for measuring the severity of maladaptive cognitions associated with mania in psychiatric patients.

Comparison between the results of the Symptom Checklist-90 in two different populations with temporal lobe epilepsy.

We performed a prospective psychopathological analysis of two distinct populations with temporal lobe epilepsy (TLE), medically treated patients (n=18) and patients surgically treated for mesial temporal sclerosis (n=19), and compared the psychopathology in the surgical population pre- and postoperatively. The Symptom Checklist-90 (SCL-90) was administered to both groups, with the surgical patients being tested before and 6 months after surgery. A multivariant comparison of the SCL-90 subscales was made between medically treated patients and patients before and after surgical treatment. Surgically treated patients had less psychopathology after surgery than before. The comparison of surgically treated patients with medically treated patients showed statistically significant differences in most subscales. Except for the subscale of Hostility, no statistically significant differences were found between medically treated patients and the surgical population before lobectomy.

Evaluation of validity of items for a food behavior checklist.

OBJECTIVES: To evaluate the validity of food behavior items, using a biological measure (serum carotenoids) as the criterion for validity of fruit and vegetable intake, and the results from multiple 24-hour recalls to test convergent validity with nutrient intake. DESIGN: Participants responded to 39 food-behavior questions and later completed three 1-day dietary recalls. Serum carotenoid levels were determined for a 59% randomly selected subsample. SUBJECTS/SETTING: A convenience sample of 100 English-speaking, low-income women participating in a Food Stamp Nutrition Education Program in 8 California counties. Statistical analyses Spearman correlation coefficients were calculated between responses to the food behavior items and (a) serum carotenoid levels and (b) mean nutrient intakes from the 24-hour recalls. Cronbach's coefficient alpha was determined for items within broad food behavior topics. RESULTS: Responses to 10 food behavior items were significantly correlated with serum carotenoid levels (correlations greater than 0.45 were found for choosing low-fat foods and a self-evaluation of overall dietary quality). An additional 12 items showed hypothesized associations with the 24-hour recall data (with a maximum correlation 0.50 for number of eggs per week and dietary cholesterol). Cronbach's coefficient alpha ranged from 0.28 (for 5 fat and cholesterol items) to 0.79 (for 9 fruit and vegetable items). APPLICATIONS/CONCLUSIONS: Nutrition professionals can use these methods to validate items for food behavior checklists for specific populations. The items described here may be useful when designing instruments to administer to low-income women in a community setting.

Use of the Child Behavior Checklist and DSM-III-R diagnosis in predicting outcome of children's social skills training.

A standardized 12-week cognitive-behavioral social skills package in which parents assisted children with socialization homework assignments, was presented to 52 nonpsychotic outpatient boys, many of whom were diagnosed with DSM-III-R Attention Deficit-Hyperactivity Disorder and Oppositional Defiant Disorder. Results demonstrated that the Thought Problems factor of the mother-completed Child Behavior Checklist aided in predicting changes in teacher-rated aggression. DSM-III-R diagnosis of Oppositional Defiant Disorder predicted changes in teacher-rated withdrawal subsequent to treatment. The need for research to determine which children benefit from which treatment was discussed.

The validity of the PTSD checklist as a measure of symptomatic change in combat-related PTSD.

Little research to date has examined the ability of self-report measures to assess changes in symptom severity and diagnostic status as a function of treatment. This study investigated the validity of the posttraumatic stress disorder (PTSD) checklist (PCL) as a measure of symptomatic change following programmatic treatment. A sample of 97 Vietnam veterans with combat-related PTSD was assessed using the clinician-administered PTSD scale (CAPS) and the PCL prior to, and 9 months following, participation in a PTSD treatment program. Using the CAPS as the "gold standard" measure of PTSD symptomatology, the PCL demonstrated high diagnostic accuracy pre- and posttreatment. However, significant variations in accuracy were evident in the ability of the PCL to determine the presence and severity of individual symptoms at each time point. In addition, as symptoms improved from pre- to posttreatment, and approached the threshold criteria, the PCL demonstrated reductions in diagnostic accuracy. As a measure of overall symptomatic change, the PCL underrated improvement in comparison to the CAPS. The results supported the use of an overall cut-off score of 50 on the PCL for a diagnosis, and an item score of 3 for symptom criterion, in this population.

[A study of the psychometric properties of the Icelandic translation of Obsessive Thoughts Checklist (OTC) with confirmatory factor analysis].

The Obsessive Thoughts Checklist (OTC) differs from several other measures of obsessive-compulsive symptoms in its focus on obsessive thoughts instead of compulsive behaviour. The OTC has been used in several studies in France and abroad and support for the discriminant and convergent validity of the instrument has been gathered. The authors of the OTC recently reported 3 underlying factors in this instrument: a perfectionism/verification factor, a contamination factor and a responsibility factor. In an earlier study of the OTC a 2 factor solution was however suggested. It therefore seems important to further elucidate the factorial structure of this instrument using confirmatory factor analysis. In this study data on the Icelandic translation of the OTC from three samples of Icelandic college students were submitted first to an exploratory and then to a confirmatory factor analysis. The total number of subjects was 614 college students, 254 men and 360 women with a mean age of 24.4 (sd = 5.0). The results of the exploratory factor analysis (PCA) submitted to a varimax rotation are presented in table I. The 3 expected factors were reproduced with few cross-loadings. In the confirmatory factor analysis the fit of three models to the data were evaluated: a 1 factor model, the 2 factor model of Bouvard et al. and the 3 factor model of Bouvard et al.. An initial examination of the data led to logarithmic transformation of 18 items to reduce skewness in their distributions. The data was subsequently subjected to a confirmatory factor analysis to compare the three-factor model with the two-factor and one-factor models for the OTC. The factors for the three- and two-factor models were allowed to correlate freely. The data were analysed using the EQS procedure, and the models tested were covariance structure models. Table II presents the goodness of fit indices for all three models. The results show that none of the three models provide an overall appropriate fit for the data. However, the fit indices for the three-factor model were considerably higher than found for the two or one factor models and the RMSEA index for the three-factor model suggested an acceptable fit for that model. Although the three-factor model suggests the best fit of all three models, the fit indices were still unacceptably low. Further examination of the data revealed a pattern of standardized residuals suggesting that this might in part be attributable to three items from the responsibility factor (items 26, 19 and 15) not being well specified within the model. When the residuals for these items were allowed to correlate, the fit of the model was substantially improved (CFI = 0.85; GFI = 0.87; AGFI = 0.85; RMSEA = 0.062). This indicates that a revision of the responsibility scale might be appropriate. Table III provides the means, standard deviations and the alpha coefficients for the 3 subscales of the OTC as well as for the total scale. In one subsample of the study (sample 1, n = 169) the OTC was administered together with the Padua Inventory-Washington State Revision (PI-WSUR) measuring obsessive-compulsive symptoms, the Penn State Worry Questionnaire (PSWQ) and the Community Epidemiological Scale-Depression (CES-D) measuring depression. In order to investigate the convergent validity and divergent of the OTC its correlation with the PI-WSUR was compared with its correlations with PSWQ and CES-D. These correlations shown in table IV support the convergent and divergent validity of the OTC. In another subsample of the study (sample 2, n = 296) the OTC was administered together with the Maudsley Obsessive Compulsive Inventory (MOCI). For samples 1 and 2, zero order and partial correlations were calculated between the subscales of the OTC and the subscales of the other instruments. As shown in table V the strongest correlations between the checking/perfectionism and the contamination subscales of the OTC were with corresponding subscales of the PI-WSUR and the MOCI. It is concluded that the factorial, the convergent and the divergent validities of the Icelandic translation of the OTC are supported in a student population even though the somewhat suboptimal fit of the three-factor model may indicate that a revision of the responsibility factor might be in order. This should however be further studied in a clinical population.

Pediatric Symptom Checklist: screening school-age children for psychosocial dysfunction.

The Pediatric Symptom Checklist (PSC) is a 35-item screening questionnaire that is completed by parents and designed to help pediatricians in outpatient practice identify school-age children with difficulties in psychosocial functioning. The current study assessed the validity of the PSC by screening 300 children in two pediatric practices, a middle-class group practice and an urban health maintenance organization. Validity was established by comparing the results of PSC screening of 48 children with in-depth interview assessments and pediatricians' ratings. Results indicate that the PSC has a specificity of 0.68 and a sensitivity of 0.95. The screening process was well accepted by parents and pediatricians. Several children whose pediatricians' ratings had indicated adequate functioning were identified by the PSC as having substantial psychosocial dysfunction and requiring further evaluation.

Utility of the Pediatric Symptom Checklist as a psychosocial screen to meet the federal Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) standards: a pilot study.

OBJECTIVE: To examine the usefulness of the Pediatric Symptom Checklist (PSC) as the psychosocial screening measure to meet federal Medicaid/Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) standards in a low-income Hispanic community. DESIGN AND SETTING: Three hundred seventy-nine children (aged 6 to 16 years) were screened with the PSC in a 10-month period during well child visits to three clinics in Ventura and San Mateo counties in California. The PSC was available in English and Spanish and was administered both in written (paper-and-pencil) and oral formats. Follow-up services were provided for children identified as needing evaluation. RESULTS: The Cronbach alpha was high (r = 0.91) for the PSC in the whole sample and virtually identical for English, Spanish, oral, and written formats. All the PSC items were significantly associated with total score on the PSC in English, Spanish, oral, and written formats. Overall, the PSC identified 10.6% of the sample as at risk for psychosocial problems. Thirty-six children (9.5% of sample) were referred for mental health follow-up. Public health data from Ventura County showed a statistically significant increase in referrals for psychologic problems during the study period in two locations using the PSC: from 0.5% to 2.9% of the school-aged children seen. CONCLUSION: The PSC provides a feasible, well-accepted method for screening for psychosocial problems during EPSDT examinations of school-aged children. Psychosocial screening using a validated instrument such as the PSC, as well as increased efforts to refer positive screening results, track outcomes, and assess cost benefits should be essential requirements in capitated Medicaid approaches to caring for poor children.

A simplified six-item checklist for screening for fragile X syndrome in the pediatric population.

OBJECTIVE: In our general experience, about 2% of samples referred for fragile X testing showed positive results on Southern blot analysis. The aim of this project was to determine whether screening criteria could be developed to increase the proportion of positive test results without sacrificing sensitivity. STUDY DESIGN: We retrospectively analyzed nine clinical characteristics from patient records of 273 male and 62 female pediatric probands (average age, 5.7 years) referred for fragile X testing. The characteristics included mental retardation, family history of mental retardation, large or prominent ears, elongated face, attention deficit hyperactivity disorder, autistic-like behavior, simian crease, macroorchidism, and hyperextensible joints. These were scored as 2 if present, 1 If borderline present, and 0 if absent. RESULTS: Analysis of the nine characteristics identified three (simian crease, macroorchidism, and hyperextensible joints) with low frequency and statistical insignificance, which were therefore eliminated. With the use of the remaining six characteristics, If a score of 5 or more was used as the criterion for requesting fragle X testing, then close to 60% of those tests from our patient population could have been eliminated without missing any positive cases. The validity of our threshold score of 5 was subsequently confirmed among an additional six cases of fragile X syndrome. CONCLUSION: With our simplified six-item clinical checklist, 60% of testing could have been eliminated, thereby improving the cost-effectiveness of fragile X testing and increasing the proportion of cases with positive results by threefold.

Development of an adjective checklist to measure five FACES of fatigue and sleepiness. Data from a national survey of insomniacs.

Development and initial validation of the FACES of fatigue and sleepiness adjective checklist. An initial item pool of 65 adjectives, descriptive of fatigue, sleepiness and related deprivation states, was developed and administered to 372 individuals referred by their family physicians for psychiatric investigation and treatment of severe insomnia. Participants attended one of six Canadian university-affiliated sleep clinics where they completed a psychiatric assessment and a 766-item questionnaire, including a number of standard indices of sleep-related behavior and symptoms, medical history, sleep hygiene, psychosocial well-being and psychopathology. Principal-components and item analyses were undertaken to refine the initial 65-item pool to a smaller 50-item set, consisting of five subscales: Fatigue, Anergy, Consciousness, Energized and Sleepiness. Coefficient alpha was calculated and indicated high internal consistency reliability for all subscales. Convergent and discriminant validity were also evaluated by calculating correlations between FACES subscales and a number of independent indices. The resulting five-scale FACES questionnaire appears to offer a promising self-report instrument for the measurement of fatigue and related subjective experiences.

A symptom checklist to screen for somatoform disorders in primary care.

Current DSM-IV somatoform diagnoses may inadequately capture many somatizing patients in primary care. By using data from two studies (1,000 and 258 patients, respectively), the authors determined 1) the optimal threshold on a checklist of 15 physical symptoms to screen for a recently proposed somatoform diagnosis, multisomatoform disorder (MSD), and 2) the concordance between MSD and somatization disorder. The optimal threshold for pursuing a diagnosis of MSD was seven or more physical symptoms. The majority (88%) of the patients who met criteria for MSD had either full or abridged somatization disorder. MSD was intermediate between abridged and full somatization disorder in terms of its association with functional impairment, psychiatric comorbidity, family dysfunction, and health care utilization and charges.

Checklist for ruling out pregnancy among family-planning clients in primary care.

Where pregnancy tests are unavailable, health providers, fearing possible harm to fetuses, often deny contraception to nonmenstruating clients. In Kenya, a trial of a simple checklist to exclude pregnancy showed a good negative predictive value, which could improve access to service and reduce unwanted pregnancies and their sequelae.

The Trauma Symptom Checklist for Young Children (TSCYC): reliability and association with abuse exposure in a multi-site study.

OBJECTIVE: The Trauma Symptom Checklist for Young Children (TSCYC) is a 90-item caretaker-report measure of children's trauma- and abuse-related symptomatology. It contains two reporter validity scales and eight clinical scales [Post-traumatic Stress-Intrusion (PTS-I), Post-traumatic Stress-Avoidance (PTS-AV), Post-traumatic Stress-Arousal (PTS-AR), Post-traumatic Stress-Total (PTS-TOT), Sexual Concerns (SC), Dissociation (DIS), Anxiety (ANX), Depression (DEP), and Anger/Aggression (ANG)], as well as an item assessing hours per week of caretaker contact with the child. This paper introduces the TSCYC and describes its psychometric properties in a multisite validity study. METHOD: A total of 219 TSCYCs administered by six clinician/researchers across the United States were analyzed for scale reliability and association with several types of childhood maltreatment. RESULTS: The TSCYC clinical scales have good reliability and are associated with exposure to childhood sexual abuse, physical abuse, and witnessing domestic violence. The PTS-I, PTS-AV, PTS-AR, and PTS-TOT scales were most predictive, followed by SC in the case of sexual abuse and DIS in the case of physical abuse. There were a small number of age, sex, and race effects on TSCYC scores. CONCLUSIONS: The TSCYC appears to have reasonable psychometric characteristics, and correlates as expected with various types of trauma exposure. Subject to continued validation and the development of general population norms, its use as a clinical measure is supported.

Validation of the PTSD checklist in an HMO sample of women.

Although Post-traumatic Stress Disorder (PTSD) is common among patients seeking care at medical clinics, little is known about the performance of screening instruments for this disorder in these settings. Previous studies of acute trauma populations using the PTSD Checklist (PCL) have suggested that scores of 45-50 provide the best discrimination between cases and noncases. We gave the PCL to 1,225 randomly selected women enrolled in an HMO. After interviewing a sample of 261 of these women using a structured, clinician-administered PTSD interview, we compared the results of the PCL to the clinician interviews over a range of possible cut scores using Receiver Operating Characteristic analysis. The optimum balance of sensitivity and specificity for this population was a score of 30, yielding a sensitivity of.82 and specificity of.76. The positive and negative likelihood ratios for this cut score were 3.40 and 0.24, respectively. By comparison, the use of 45 as a cut score would result in very low sensitivity (.36) in this setting. The lower cut score found in this study may indicate that the use of previously published cut scores of 45-50 may not optimize the function of the PCL as a screening tool outside of acute trauma settings due to an unacceptably high number of false negative cases.

Screening for post-traumatic stress disorder in female Veteran's Affairs patients: validation of the PTSD checklist.

We evaluated the screening validity of a self-report measure for post traumatic stress disorder (PTSD), the PTSD Checklist (PCL), in female Veterans Affairs (VA) patients. All women seen for care at the VA Puget Sound Health Care system from October 1996-January 1999 (n=2,545) were invited to participate in a research interview. Participants (n=282) completed the 17-item PCL, followed by a gold standard diagnostic interview for PTSD, the Clinician Administered PTSD Scale (CAPS). Thirty-six percent of the participants (n=100) met CAPS diagnostic criteria for current PTSD. Receiver Operating Characteristic (ROC) analysis was used to evaluate the screening performance of the PCL. The area under the ROC curve was 0.86 (95% CI 0.82-0.90). A PCL score of 38 optimized the performance of the PCL as a screening test (sensitivity 0.79, specificity 0.79). The PCL performed well as a screening measure for the detection of PTSD in female VA patients.

Psychometric properties of the non-communicating children's pain checklist-revised.

The non-communicating children's pain checklist (NCCPC) has displayed preliminary validity and reliability for measuring pain in children with severe cognitive impairments (Dev Med Child Neurol 42 (2000) 609). This study provides evidence of the psychometric properties of a revised NCCPC (NCCPC-R) with a larger cohort of children. Caregivers of 71 children with severe cognitive impairments (aged 3-18) conducted observations of their children using the NCCPC-R during a time of pain and a time without pain. Fifty-five caregivers completed a second set of observations. The score results on the NCCPC-R were: internally consistent, significantly related to pain intensity ratings provided by caregivers, consistent over time, sensitive to pain, and specific to pain. Analyses of children's individual scores indicated up to 95% of their scores were consistent. Receiver operating characteristic curves suggest a score of 7 or greater on the NCCPC-R as indicative of pain in children with cognitive impairments, with 84% sensitivity and up to 77% specificity. These results provide evidence of NCCPC-R having excellent psychometric properties.
