Construct validity of Cyriax's selective tension examination: association of end-feels with pain at the knee and shoulder.

STUDY DESIGN: Descriptive. OBJECTIVES: To examine the relationship between pain and normal and abnormal-pathologic end-feels during passive physiologic motion assessment at the knee and shoulder. We theorized that abnormal-pathologic end-feels would be more painful than normal end-feels. BACKGROUND: End-feel testing and pain intensity information are part of physical therapy musculoskeletal patient examinations. End-feels are categorized as normal or abnormal-pathologic. No previous studies have examined the relationship between pain during end-feel testing and the type of end-feel. METHODS AND MEASURES: Two physical therapists examined subjects with unilateral knee or shoulder pain. Each subject was examined twice. Passive physiologic motions, 2 at the knee and 5 at the shoulder, were tested by applying an overpressure at the end of range of motion using standardized positions. Subjects reported the amount of pain (0-10) immediately after the evaluator recorded the end-feel. Analyses included one-way ANOVAs and post-hoc Tukey's Honestly Significant Difference tests. RESULTS: Some abnormal-pathologic end-feels were significantly more painful than the normal end-feels at both the knee and the shoulder for all physiologic motions. Among the abnormal-pathologic end-feel categories there were no statistical differences in pain intensity, although small samples in some categories may be responsible for this finding. CONCLUSION: Abnormal-pathologic end-feels are associated with more pain than normal end-feels during passive physiologic motion testing at the knee or shoulder. Dysfunction should be suspected when abnormal-pathologic end-feels are present.

Construct validity of the Denman Memory for Human Faces test.

Assessed the validity of the Denman Memory for Human Faces (MHF) subtest employing a clinical sample. Factor analysis with marker variables was employed to establish the nature of the extracted factors. The MHF subtest, WAIS-R Verbal (i.e., Information, Vocabulary, and Digit Span) and Performance (i.e., Block Design and Object Assembly) subtests, the Wechsler Memory Scale Mental Control, Paired Associate Learning, 30-min Logical Memory, and 30-min Visual Reproduction, and Benton's Facial Recognition Test were subjected to a maximum likelihood factoring procedure with Varimax rotation. Four factors were extracted which accounted for 72.7% of the variance. Factor I was perceptual-organization, Factor II was verbal comprehension, Factor III was general memory, and Factor IV was attention-concentration. The MHF subtest achieved a substantial loading (i.e., 0.56) on the general memory factor along with Logical Memory (0.54), Visual Reproduction (0.51), and Paired Associate Learning (0.71). Clinical applications of the MHF were discussed.

The reliability and construct validity of two measures of addictive personality.

Gossop and Eysenck developed a subscale of the EPQ that discriminates between drug addicts in treatment and nonaddicts. They called this scale the Addiction Scale (AS). Previously, MacAndrew developed an Alcoholism Scale (MAC) by comparing alcoholics and nonalcoholic psychiatric patients' responses on the MMPI. In the present report both scales were completed by 615 men and 642 women as part of the Winnipeg Health and Drinking Survey, a longitudinal study of personality and health. The reliability of both scales is quite low, .64 for the AS and .57 for the MAC. Correlations with other personality measures indicate that the MAC is more associated with extraversion-related characteristics whereas the AS is more associated with neuroticism-related factors. The AS was not associated with the level of smoking, and the MAC was correlated with smoking for men only. Both scales were significantly correlated with various drinking measures, and the correlations were slightly higher for the MAC.

Construct validity of stages of change for exercise behavior.

PURPOSE: Previous research examining the transtheoretical model of behavior change within the exercise domain has been limited by use of self-report measures exclusively and inconsistent practices with regard to stage of exercise assessment. The present study was designed to partially circumvent these limitations and extend the current literature by determining the degree of association among stage of exercise and body mass index, cardiorespiratory fitness, exercise behavior, relapse, barriers, and self-efficacy, after controlling for several potential confounders. DESIGN: A descriptive, cross-sectional study. SUBJECTS: Two hundred thirty-five adults (M age = 34.7 years) volunteered to participate. MEASURES: Participants were classified by stage of exercise and compared on two behavioral, two biometrical, and three psychological variables while statistically controlling for social desirability and demographic differences. RESULTS: Significant between-stage differences were found for the overall set of dependent variables (p < .0001) and for each dependent variable separately (p < .01). The proportion of variance accounted for by the dependent variables ranged from .06 to .53. CONCLUSIONS: This study offers objective support for the stage-of-change model within the exercise domain. By acknowledging and accurately assessing stage of exercise, researchers and clinicians may be able to improve physical activity promotion efforts.

Occupational Case Analysis Interview and Rating Scale. An examination of construct validity.

The Occupational Case Analysis Interview and Rating Scale (OCAIRS) was developed based on the Model of Human Occupation with the intention of assessing patients' occupational adaptation. Several studies examining the quality of this instrument have been completed; however, none have discussed the internal validity of the instrument or the appropriateness of the rating scale. The purpose of this study is to validate the internal validity of the OCAIRS and to test the quality of the rating scale. The results indicate that the OCAIRS is a valid measure of occupational adaptation. Each item was shown to have its own rating scale structure, however, all items together still shared the same five-point rating scale.

Construct validity of the PCSQ as related to the MMPI-2.

The Postconcussion Syndrome Questionnaire (PCSQ) total and factor scores were compared to the primary validity and clinical scales from the Minnesota Multiphasic Personality Inventory-II (MMPI-2) in an effort to better define the structure of the PCSQ. The sample used was composed of a heterogeneous group of 79 patients referred for clinical neuropsychological evaluation. In reviewing the results, patients with higher PCSQ scores presented with higher clinical elevations on the MMPI-2. In addition, each of the PCSQ factor scores was related to a different pattern of MMPI-2 scales and subscales. The somatic factor was most associated with physical ailments, generalized distress, and social insecurity. In contrast, the psychological factor was related to complaints of dysphoria, brooding, and social connectedness. The cognitive and infrequent factors were related to reports of cognitive changes and unusual sensory experiences, respectively. The data present validation of the multifaceted nature of the PCSQ and its general sensitivity to subjective complaints.

An exploration of the construct validity of the Heaton memory tests.

The Heaton techniques for assessing memory differ from most other memory measures by employing the combination of learning trials, repeated exposure to test stimuli, and 4-hour recall measures. The present study was designed to explore the relationship between the Heaton Story and Figure memory procedures, the California Verbal Learning Test (CVLT), and measures of attention, word fluency, and spatial perception. Data from 126 individuals were analyzed. Three separate factor analyses were performed that examined measures of attention, learning, and recall. Each revealed a three-factor solution accounting for 71, 70, and 72% of the variance, respectively. Regression analyses supported the visual components of Figure Memory and the verbal components of Story Memory obtained in the factor analyses. Overall, the findings supported the independence of the Heaton Memory procedures and the role of spatial factors in performance of Figure Memory. Additionally, both Figure and Story Memory shared variance with the CVLT, supporting the validity of both procedures as memory measures.

The construct validity of the Lees-Haley Fake Bad Scale. Does this scale measure somatic malingering and feigned emotional distress?

The Fake Bad Scale (FBS [Psychol. Rep. 68 (1991) 203]) was created from MMPI-2 items to assess faking of physical complaints among personal injury claimants. Little psychometric information is available on the measure. This study was conducted to investigate the psychometric characteristics of the FBS using MMPI-2 profiles from six settings: Psychiatric Inpatient (N=6731); Correctional Facility (N=2897); Chronic Pain Program (N=4408); General Medical (N=5080); Veteran's Administration Hospital Inpatient (N=901); and Personal Injury Litigation (N=157). Most correlations of the FBS and raw scores on the MMPI-2 were positive with correlations among the validity scales being lower than correlations among the clinical and content scales. The FBS was most strongly correlated with raw scores on Hs, D, Hy, HEA, and DEP. When the more conservative cutoff of 26 was used, the FBS classified 2.4-30.6% of individuals as malingerers. The highest malingering classification was for the women's personal injury sample (37.9%) while the lowest was among male prison inmates (2.3%). Compared to men, in most samples, almost twice as many women were classified as malingerers. The results indicate that the FBS is more likely to measure general maladjustment and somatic complaints rather than malingering. The rate of false positives produced by the scale is unacceptably high, especially in psychiatric settings. The scale is likely to classify an unacceptably large number of individuals who are experiencing genuine psychological distress as malingerers. It is recommended that the FBS not be used in clinical settings nor should it be used during disability evaluations to determine malingering.

Clinical examination variables discriminate among treatment-based classification groups: a study of construct validity in patients with acute low back pain.

BACKGROUND AND PURPOSE: Treatment-based classification (TBC) provides matched interventions for patients with acute low back pain (LBP) through key history and clinical findings. This study investigated the discriminant validity of TBC by determining whether commonly used clinical examination variables discriminated among TBC groups. SUBJECTS: The mean age of the 131 participants was 37.7 years (SD=10.1), 66 participants (50.4%) were female, mean duration of LBP was 16.5 days (SD=16.1), and 60 participants (45.8%) had a prior history of LBP. Fifty-one study participants (38.9%) were classified for specific exercise, 42 (32.1%) for mobilization, 28 (21.4%) for immobilization, and 10 (7.6%) for traction. METHODS: One-way analyses of variance and Kruskal-Wallis tests were used to investigate differences in clinical variables by TBC group. Then, discriminant function analysis (DFA) predicted TBC group membership. RESULTS: The TBC groups differed on present pain intensity, duration of LBP, and history of LBP. Present pain intensity, duration of LBP, total lumbar flexion, presence of leg pain, and history of LBP produced 2 statistically significant discriminant functions that predicted TBC group membership. These functions correctly classified (cross-validation value in parentheses) 65% (65%) for specific exercise, 45% (40%) for mobilization, and 32% (32%) for immobilization. DISCUSSION AND CONCLUSION: This study provided evidence supporting the discriminant validity of TBC. Additional diagnostic information related to TBC groups was generated.

Psychometric properties of the bath ankylosing spondylitis disease activity index (BASDAI): comparison of the different versions available in English.

OBJECTIVE: International ASAS consensus statement proposed the use of the BASDAI to evaluate active disease in ankylosing spondylitis patients before the use of anti-TNF agents. To analyze the psychometric properties of the different versions of the BASDAI. METHODS: All versions available in English were analyzed according to the methods developed by the American Psychological Association. Except for the initial version, the procedure of translation was accepted if a translation followed by a back translation was carried out. The psychometric properties analyzed were: face validity, content validity, construct validity (factorial analysis, convergent and divergent validity), reliability (test retest, Cronbach's coefficient alpha), and responsiveness. RESULTS: Except for the German version which was not available in English, the following versions were analyzed: English (En), French (Fr), Swedish (Sw), Spanish (Sp), and Turkish (Tu). The procedure translation was correct in all the versions without taking into account the initial En version. Face validity was validated in all versions. No version initially defined the dimensions for the content validity. Construct validity was partially studied and validated in En, Fr and Sp. Reliability was validated in En, Fr, Tu, and partially in other versions. In all versions, except for the Fr, responsiveness was demonstrated. CONCLUSION: The English version of the BASDAI is the most validated tool. Some efforts had to be made to continue the validation procedure of all versions of the BASDAI. This is an important step for further international comparison.

[Construction, validity and reliability, of the screening scale "FASCT" for attention deficit hyperactivity disorder in adults (self-reported and observer versions)].

INTRODUCTION: Research about the reliability of retrospective self-report rating scales for attention deficit hyperactivity disorder (ADHD) in adults has been limited. METHOD: A self-report scale named "FASCT" was created with two versions: self-reported and observer. The self-reported version was applied to 393 subjects and the observer version to 377. An exploratory and confirmatory factorial analysis was made in order to obtain the final adaptation of both versions. Finally they were applied to 205 subjects and 105 of their first degree relatives. RESULTS: Cronbach's alpha for the self-reported version was 0.84 and 0.87 for the observer version. The total score that had the best balance between sensitivity and 1-specificity was 23 points for each version of the "FASCT". Correlation between both versions was 0.88. The correlation coefficient between the Wender-UTAH scale and self-reported version was 0.71 and for the observer version was 0.66. Agreement degree between dichotomized total score and the diagnosis made by structured interview was 0.82, for the self-reported version and 0.88 for the observer version. Sensitivity and specificity for the self-reported version were 80.36 and 97.9, respectively. Sensitivity and specificity values for the observer version were 95.4 and 96.3 respectively. CONCLUSIONS: Both versions of the "FASCT" scale were shown to be valid and reliable for adult ADHD screening.
