Acceptance of pain is an independent predictor of mental well-being in patients with chronic pain: empirical evidence and reappraisal.

This paper reports upon: (1) the value of acceptance of pain in predicting well-being in patients suffering from chronic pain and (2) the construct validity of acceptance by comparing two questionnaires designed to measure acceptance (the Chronic Pain Acceptance Questionnaire, CPAQ, unpublished doctoral dissertation, University of Nevada, Reno, NV, 1992 and the Illness Cognitions Questionnaire, ICQ, J Consult Clin Psychol 69 (2001) 1026). The results of two independent cross-sectional studies are reported. Study 1 included 120 patients seeking help in tertiary care settings. In Study 2, 66 patients were recruited from a self-support group for fibromyalgia patients and from a pain clinic. Both studies revealed that acceptance of pain predicted mental well-being beyond pain severity and pain catastrophizing, but did not account for physical functioning. In both instruments, it was found that acceptance of pain was strongly related to engagement in normal life activities and the recognition that pain may not change. Acceptance in both instruments was strongly related to a cognitive control over pain. Study 2 further revealed that the correlation between the CPAQ and the ICQ is moderate, indicating that both instruments measured different aspects of acceptance. It is concluded that acceptance of chronic pain is best conceived of as the shift away from pain to non-pain aspects of life, and the shift away from a search for a cure with an acknowledgement that pain may not change.

Validity and reproducibility of a self-administered questionnaire to determine dietary supplement users among Japanese.

OBJECTIVE: To evaluate reproducibility and validity of a self-administered food frequency questionnaire (FFQ) to determine the dietary supplement use. DESIGN: Questionnaire data were compared with dietary records (DR) in four 7 day periods for validity. FFQ1 and FFQ2 administered at an interval of approximately one year were compared for reproducibility. SETTING AND SUBJECTS: A total of 361 samples were selected for a validation study of a questionnaire from the subgroup of the Japan Public Health Center-based prospective Study on cancer and cardiovascular disease (JPHC Study) cohort II. Categories of dietary supplements in the FFQ were 'multivitamins', 'beta-carotene', 'vitamin C', 'vitamin E', and 'other supplements'. For each category, inquiries were made as to the brand name, frequency and duration of use. A dietary supplement user was defined as a subject who used a dietary supplement one or more times a week for a year or longer. RESULTS: Prevalence of overall supplement use was 10.9%. Percentage agreement between FFQ1 and FFQ2 was 91.7%. Sensitivity and specificity of supplement use by FFQ were 80.6% and 89.2%, respectively. Sensitivity was high for 'vitamin C'. When the self-reported categories were corrected, sensitivity for 'multivitamins' and 'vitamin E' improved. CONCLUSIONS: The FFQ on dietary supplements used for the JPHC 5 y follow-up survey was valid to determine overall use and well-defined dietary supplement use such as vitamin C. Categories must be corrected when determining multivitamin and 'vitamin E'.

Validation of a soy questionnaire with repeated dietary recalls and urinary isoflavone assessments over one year.

This study assessed the validity and reliability of a 12-item soy questionnaire designed for use in cancer prevention research. The questionnaire measures soy intake over the past year. Subjects were 199 healthy 35- to 46-yr-old premenopausal women participating in an ongoing soy intervention study. Soy questionnaire estimates of isoflavone intake over 1 yr were compared with individual and combined estimates from two reference measures covering the same period: three or four repeated 24-h recalls and one or two repeated urine analyses. The sensitivity and specificity of the soy questionnaire in classifying high vs. low exposure (high exposure = soy intervention group membership) were comparable with 24-h recalls and were superior to urine analyses (sensitivity = 94.8%, 97.9%, and 71.1%; specificity = 95.1%, 97.1%, and 90.3% for the soy questionnaire, 24-h recalls, and urine analyses, respectively). Soy questionnaire isoflavone estimates were highly correlated with the combination of the two reference measures for the entire study population. Its brevity, ease of administration, and good measurement properties over a 1-yr period make the soy questionnaire well suited to the needs of researchers who wish to identify high and low consumers of soy foods, especially in populations who consume traditional Asian soy foods.

Deciding to exercise: the role of anticipated regret.

OBJECTIVES: Two studies tested (a) whether anticipated regret (AR) qualifies as an additional predictor of intentions to engage in a health-enhancing behaviour (exercise) after variables from the Theory of Planned Behaviour (TPB) and past behaviour have been controlled, and (b) whether a manipulation that induces participants to focus on AR causes stronger intentions to exercise. DESIGN: Study 1 employed a cross-sectional questionnaire design; Study 2 employed a between-participants experimental design (AR focus vs. no AR focus). METHOD: Participants (N = 385) completed standard, multi-item, reliable measures of TPB constructs and AR and also reported their past behaviour (Study 1). Participants in Study 2 (N = 70) completed measures of AR and intention; salience of AR was manipulated by means of item order. RESULTS: Study 1 showed that even though TPB variables and past behaviour were reliable predictors of intention, and explained 51% of the variance, AR contributed a substantial increment in the variance (5%) even after these predictors had been taken into account. Study 2 showed that participants who were induced to focus on AR prior to intention formation had significantly stronger intentions to exercise compared to controls. CONCLUSION: The findings indicate that AR predicts a health-enhancing behaviour (as well as the health-risk behaviours examined in previous research) and that effects of AR are independent of TPB variables and past behaviour. The findings also indicate that a simple and inexpensive manipulation of the salience of AR can be used to promote exercise intentions.

Reproducibility and validity of a postal questionnaire. The abdominal symptom study.

OBJECTIVE: To find out whether it is possible to examine abdominal/gastrointestinal symptoms by a postal questionnaire. DESIGN: In the Abdominal Symptom Study a postal questionnaire was sent to a representative sample of adults (n = 1290) on two occasions, one year apart. The questionnaire was sent a third time to a subsample (n = 110), and to another sample (n = 213) who had not seen the questionnaire before. A subsample (n = 150 of the 1290) was subjected to a medical interview and examination. SETTING: The municipality of Osthammar, Sweden. PARTICIPANTS: A sample (9.3%) of all Swedish citizens (20-79 yrs) in the municipality. MAIN OUTCOME MEASURE: Reproducibility and validity of a postal questionnaire. RESULTS: The response rate was 90%. Roughly 50% of the study population reported abdominal symptoms. The reproducibility of the results was satisfactory, as was the validity of the questionnaire evaluated by medical interview and examination. Non-responders did not report more symptoms than responders. CONCLUSION: It is possible to examine abdominal/gastrointestinal symptoms with a postal questionnaire. The questionnaire used in The Abdominal Symptom Study seems to be useful for this purpose.

[The comparison of tianeptine and carbamazepine in benzodiazepines withdrawal symptoms].

Dealing with benzodiazepine dependent creates as serious clinical problem that requires knowledge and experience. Abrupt discontinuation of benzodiazepines, particularly those with short half-life is not advised to avoid severe withdrawal syndrome. Reports from literature suggest use of carbamazepine and recently tianeptine as substances useful in treatment of benzodiazepine dependence. This paper presents a double-blind trial in which both, carbamazepine and tianeptine were used in treatment of benzodiazepiene withdrawal syndrome. Patient mental state was evaluated by using questionnaire SCL-90, Beck Depression Inventory and specifically designed questionnaire assessing severity of symptoms following benzodiazepine withdrawal. It appears from this study that both drugs (carbamazepine and tianeptine) are comparable, safe and efficient in treating benzodiazepine withdrawal symptoms.

Use of psychometric techniques in the analysis of epidemiologic data.

PURPOSE: This article demonstrates techniques for developing reliable multi-item scales for analysis of complex public health data. METHODS: Information from a questionnaire designed to evaluate the acceptability and efficacy of the female condom as a method for STD/HIV prevention was summarized using psychometric analysis. 1159 high-risk women attending STD clinics participated in this study. Questionnaire items were designed to measure nine domains of predictors of condom use. RESULTS: Principal components analysis was employed to reduce the number of potential predictors. Reliability of the multiple-item scales was assessed using Cronbach's alpha. Pearson's correlation coefficients were calculated to evaluate collinearity among multi-item scales. Approximately half (51%) of the questionnaire items that were analyzed were retained in the final scales. Data reduction procedures identified several multi-item scales with acceptable reliability (Cronbach's alpha >0.70). The correlation coefficients between scales was never >.5, suggesting that there was little collinearity among the scales. CONCLUSIONS: When focused on multiple partially interdependent determinants of an outcome, data reduction decreases the number of independent variables to be evaluated, ensures they have adequate reliability, maximizes strength of their association with outcomes, and reduces collinearity among predictors.

A rationale for assessing sports activity levels and limitations in knee disorders.

Existing published knee rating systems that assess sports participation, knee function, and subjective symptomatology following ligamentous surgical procedures were analyzed. Major errors in questionnaire design and data reduction have led to invalid conclusions. A questionnaire containing a minimum set of rating criteria was formulated to validly assess athletic participation before and after treatment or surgery. Select questions and a data reduction format were established to assess the intensity of sports participation, changes in sports participation, the variables that produced the changes, self-assessed functional limitations, and the ability to participate in different types of sports. A clinical trial of the questionnaire was performed on 59 patients. An interview conducted upon completion of the questionnaire enabled the authors to detect difficulties or inconsistencies in the responses to the questions. The design format described in this report forms the basis for a subjective evaluation of ligamentous surgery. A standard format for analysis of sports participation and knee function is proposed to aid investigators in comparing variations in clinical results.

The Eating Behavior Patterns Questionnaire predicts dietary fat intake in African American women.

OBJECTIVE: To develop a behavioral assessment of eating that would be predictive of fat intake in African American women. DESIGN: Questionnaires were developed using a three-stage design, involving item generation, item refinement, and questionnaire validation. SUBJECTS: Focus groups sessions were conducted with 40 African American women, initial questionnaire development employed 80 African American women, and questionnaire validation involved 310 African American women from diverse socioeconomic backgrounds. Statistical analyses Transcripts of focus groups were used to generate 113 behavioral questionnaire items. The initial questionnaire was administered along with a food frequency questionnaire, and the item pool was reduced to 51 items. Factor analysis was used to create subscales. Correlation (r) and multiple regression analysis (R) were used to evaluate construct validity. RESULTS: Factor analysis revealed six subscales: low-fat eating, emotional eating, snacking on sweets, cultural/ethnic, haphazard planning, and meal skipping. The scales are significant predictors of micronutrient (R values from 0.22 to 0.47) and macronutrient intakes (R values from 0.33 to 0.58) assessed using a food frequency questionnaire and show construct validity in relationship to other measures of eating behavior (r values from 0.22 to 0.65). APPLICATIONS: The Eating Behavior Patterns Questionnaire (EBPQ) may be a useful tool for clinical assessment, clinical and community nutrition intervention studies, and epidemiologic research with African American women.

Communicative competence as perceived by adults with severe speech impairments associated with cerebral palsy.

The effects of aided message length (single-word vs. phrase-generated messages) and partner feedback (presence vs. absence of expanded message repetitions) on perceptions of the communicative competence of an adult augmentative and alternative communication (AAC) system user were examined. Subjects consisted of 12 nonambulatory adults with severe speech impairments associated with cerebral palsy. Four scripted videotaped conversational conditions involving the AAC system user and a typically speaking partner were employed to manipulate the two independent variables. A balanced incomplete block design was used. Following each viewing, subjects completed a questionnaire designed to assess the communicative competence of the AAC system user. Results indicated that neither independent variable had an impact on the subjects' ratings of communicative competence. Findings are compared with those from an earlier investigation, and clinical implications are discussed.

The role of an initial single-blind placebo period in phase I clinical trials.

The effect of an initial single-blind placebo period in a phase I clinical trial was assessed in 12 volunteers who underwent five weekly treatment periods, consisting of treatment on the first day and a six-day wash-out period. An initial single-blind placebo period was followed by three different single doses of a platelet-aggregation factor inhibitor and another placebo period, under a double-blind Latin square design. Reports of abnormal symptoms were collected using a questionnaire designed by our group. A total of 13 abnormal symptoms were reported during the first period and only nine for the following four periods, indicating a clear placebo period effect. These preliminary results suggest that an initial single-blind period may be usefully included in phase I clinical trials.

A study of ergonomics factors in washbasin design.

A 4-week UNESCO-sponsored mission to the Department of Architecture, Karadeniz Technical University in Eastern Turkey, gave an opportunity to apply ergonomics techniques to some aspects of that country's domestic washbasin design. The study was intended to provide experience in questionnaire design and administration, in the application of psycho-physical methods, and to highlight the importance of determining user characteristics and preferences with regard to the built environment. A field study elicited information on dimensions and positioning of existing wash-basins and ancillary equipment and the opinions of users as to the suitability of these features in relation to the activities performed. A laboratory study, using an adjustable rig permitting variation in the heights of basin, taps and mirror/shelf, followed. The data obtained on preferred heights of these items led to the conclusions that basin height should be increased to between 95 and 100 cm to satisfy the majority of users; tap height above the basin should be reduced to about 11 cm; the shelf and lower edge of a mirror sited above the basin should be 136 cm above the floor; and a clear space of 110 cm should be available between the front of the basin and a wall or other obstruction. Suggestions on other design aspects of the bathroom, resulting from the study, are discussed.

The International Study of Asthma and Allergies in Childhood (ISAAC): objectives and methods; results from German ISAAC centres concerning traffic density and wheezing and allergic rhinitis.

The International Study of Asthma and Allergies in Childhood (ISAAC) was founded to maximize the value of epidemiological research into asthma and allergic disease by establishing a standardized methodology and facilitating international collaboration and comparison of data. The ISAAC design comprises three phases: Phase I uses validated core questionnaires designed to assess the prevalence and severity of asthma and allergic disease in defined populations; Phase II will investigate possible aetiological factors suggested by findings of Phase I and apply lung, blood and skin tests; Phase III will be a repetition of Phase I after 5 years to assess time trends in the prevalence and severity of wheezing, rhinitis and eczema in each ISAAC centre. In 1991 a survey on wheezing and allergic rhinitis in 2050 12-15 year old adolescents in Bochum showed a positive correlation between the prevalence of wheezing as well as allergic rhinitis and indicators of traffic density, controlling for putative confounders such as age, sex, passive smoking, active smoking, etc. In 1994-1995 an ISAAC Phase I survey conducted on adolescents in Münster, applying methodology similar to that in Bochum, found positive associations between surrogate measures of traffic density and 12 months prevalence of wheezing and lifetime prevalence of allergic rhinitis of a magnitude very close to that found in Bochum. The results from the two German cities provide support to the hypothesis that exposure to automobile emissions is related to wheezing and allergic rhinitis in children.

Increased fruit, vegetable and fiber intake and lower fat intake reported among women previously treated for invasive breast cancer.

OBJECTIVE: To describe the dietary intake patterns of women before and after breast cancer diagnosis. SUBJECTS AND SETTING: 3,084 women (age range 27 to 70 years) who had been treated for early-stage breast cancer, who were free of recurrent disease, and who were willing to complete study questionnaires. DESIGN: A descriptive analysis of baseline demographic and lifestyle questionnaire data, including reported dietary intake data from women who have had breast cancer participating in a randomized, controlled dietary intervention trial. Outcomes include dietary intakes of high- and low-fat foods, fruits and vegetables, and whole grains. STATISTICAL ANALYSIS PERFORMED: Analyses included frequency of intake of selected food items, chi2 analysis to determine associations between reported intakes and demographic and personal characteristics, and logistic regression to assess odds of making more healthful changes. RESULTS: Women who have had breast cancer reported higher fruit, vegetable, and fiber-rich food intakes (58%, 60%, 38% more, respectively) and lower intakes of high-fat foods, including fast foods, after diagnosis. Those older than age 60 years were more likely to report no change in intake, including red meat (41%), vegetables (51%), and whole grains (62%). Odds ratios (OR) for more healthful diet choices varied by age and time since diagnosis. The longer the time since diagnosis the more likely women selected low-fat (vs high-fat) foods (OR 1.56, 95% confidence interval [CI] 1.16-2.09 for 3 to 4 years vs <1 year after diagnosis) and reduced added fats (OR 1.47, 95% CI 1.17-1.84 for 3 to 4 years vs <1 year after diagnosis). APPLICATIONS: Women who have had breast cancer report more healthful diet habits after diagnosis. Through nutrition education and counseling, dietetics professionals may be able to promote healthful and evidence-based eating habits among women previously treated for breast cancer.

The ATAC (Arimidex, Tamoxifen, Alone or in Combination) adjuvant breast cancer trial in postmenopausal patients: factors influencing the success of patient recruitment.

The ATAC ('Arimidex', Tamoxifen, Alone or in Combination) trial is a randomised, double-blind, double-dummy trial, evaluating anastrozole alone or in combination with tamoxifen compared with tamoxifen alone, as a 5-year adjuvant treatment for postmenopausal patients with early breast cancer. The rapid rate of recruitment into this trial was a major achievement, as frequently encountered differences between projected and actual recruitment rates can threaten the successful completion of clinical trials. A questionnaire designed in order to highlight possible factors influencing the success of patient recruitment was completed by 62% of the ATAC trialists. This included 11 statements rated for their level of importance on a three-point scale. The top three motives for recruiting patients were: (1) the attractive scientific rationale of the trial (84%); (2) a design that was easy to explain to patients (79%); and (3) a pragmatic trial design in line with standard practice (76%). A new questionnaire will solicit opinion from the participating patients.

Variables influencing perceptions of the communicative competence of an adult augmentative and alternative communication system user.

The effects of aided message length, partner reauditorization, and observer background on perceptions of the communicative competence of an adult augmentative and alternative communication (AAC) system user were examined. Two groups of subjects participated: naive adults with minimal exposure to nonspeaking persons, and speech-language pathologists currently working with AAC users. Four scripted videotaped conversational conditions involving an AAC user and a normally speaking partner were employed to manipulate aided message length and partner reauditorization. A balanced incomplete block design was used. Following each viewing, subjects completed a questionnaire designed to assess the communicative competence of the AAC user. Results indicated a significant interaction effect involving subject group and aided message length. The speech-language pathologists were affected by aided message length. Furthermore, significant differences between subject groups were found in specific conditions. Future research directions are discussed.

The effect of an interactive experience on music majors' perceptions of music for deaf students.

The purpose of this study was to examine the effect of an interactive experience on music majors' perceptions of music experiences for deaf students. Twenty-three members of a pre-existing college brass ensemble served as subjects, and a 1-hour interactive concert/presentation for 10 deaf elementary children served as the independent variable. The interactive experience was designed to provide social, musical, and educational interactions between the college musicians and the deaf children. A pretest-posttest design was utilized, and the dependent variable was a questionnaire designed to examine the subjects' perceptions regarding music for deaf students, including how prepared, comfortable, and willing they felt to provide music experiences for deaf students. Results reveal that this single interactive experience had a significant effect on the subjects' perceptions of the value of music in the education of deaf children (p <.05). Although the pretest and posttest scores indicate that the subjects felt apprehensive about their preparedness to work with deaf students, the subjects felt significantly more positive about their preparedness following the interaction (p <.001). An analysis of open comments indicates that the subjects perceived the experience as (a) very positive, (b) increasing their knowledge and perception of music for deaf students, (c) helping them better relate to the deaf population, (d) promoting interest in similar experiences and in gaining more information, and (e) eliciting a feeling that future teachers should have similar experiences. Quotes from the subjects are given, and implications for teacher training/music therapy programs are discussed.
