Longitudinal tracking and retention in a school-based study on adolescent smoking: costs, variables, and smoking status

Methods used to track a cohort of Grade 6 students through Grades 8 and 11, and costs involved for survey completion in school and by mail for ever and never smokers from the original group are detailed. At baseline, 1,598 students in Scarborough, Canada, completed a questionnaire on smoking, drinking, and health, and again in Grade 8 (N = 1,543/1,598) and Grade 11 (N = 1,454/1,598). In Grades 8 and 11, tracking and administering the questionnaire was more costly per participant when the survey was administered by mail than in school. Average completion costs were highest for Grade 11 students who used tobacco at baseline ($52.44). Students categorized as ever smokers in Grade 6 were harder to locate at each phase of testing, which suggests that this group should be identified at baseline so that closer tracking procedures may be employed between data collection points.     

Does questionnaire structure influence response in postal surveys?

This study tested the effect of questionnaire structure on response, speed of return, and content of answers in a postal survey. All 259 patients aged 30-59 years who consulted with back pain at four UK general practices from March to June 2001 were randomly allocated to receive either a traditionally or chronologically structured self-completion questionnaire. The response was higher and the returns quicker (P =.05) for the chronologic questionnaire. There were no statistically significant differences in completion rates or scores on the SF-36, Chronic Pain Grade, Hospital Anxiety and Depression Scale, or Roland-Morris Disability Questionnaire between the two types of questionnaire, and test-retest reliability was high for all scales. Changing questionnaire structure to make questions chronologic does not substantially affect the answers given, but may make a questionnaire more acceptable and easier to complete and speed up returns.     

A reproductive health survey on unintended pregnancy in Yamagata, Japan: feasibility of the survey and test-retest reliability and validity of a questionnaire

We have designed a survey to investigate factors related to unintended pregnancy using a newly devised questionnaire. This pilot study was conducted to examine the feasibility of the study and the test-retest reliability and the validity of the questionnaire. Samples were 107 cervical and breast cancer screening participants aged 35-49 year-old in 1999 in Yamagata, Japan. The same questionnaires were mailed twice to examine the test-retest reliability. Women's medical records for cancer screening were used to examine the validity of the questionnaire. Ninety-six women agreed to participate in the study and 89.6% of them responded to the first survey. The agreements between two surveys were substantial to perfect for the nominal and ordinal data, and for the continuous data, the standard deviations (SDs) were less than 1 and the correlation coefficients were over 0.6. The comparison between medical record and questionnaire derived data showed perfect agreements for reproductive items except age at last birth (SD: 0.71, correlation coefficient: 0.97), and fair agreements for drinking and smoking habits. Obtaining information on unintended pregnancy by questionnaire is feasible, and the test-retest reliability and the validity of the questionnaire are satisfactory. Currently we are conducting a survey with a larger sample.

The development and validation of a short measure of functioning and well being for individuals with Parkinson's disease

Parkinson's disease is a common degenerative neurological condition. A number of general health status measures exist but these may not address areas salient to specific diseases. We report here the development and validation of a short 39 item health status questionnaire for use in Parkinson's disease. Questionnaire items, generated from indepth interviews with people with Parkinson's disease, were developed into a 65 item questionnaire. Data from a postal survey using the 65 item questionnaire were statistically analysed to produce a shorter questionnaire with 39 items and eight scales addressing different dimensions of Parkinson's disease. A second postal survey was conducted in order to assess the reliability and validity of the new 39 item questionnaire. The final questionnaire, referred to here as the 39 item Parkinson's Disease Questionnaire (PDQ-39), proved to have satisfactory internal and test-retest reliability, and construct validity in relation to other measures, reported by respondents with Parkinson's disease.

A new, brief questionnaire (PEQ) developed in primary health care for measuring patients' experience of interaction, emotion and consultation outcome

BACKGROUND: A deepened understanding of patients' perspectives is essential in order to improve medical communication. By changing focus from patient satisfaction to patient experiences, more immediate, personal and affective responses may be captured. OBJECTIVE: Our aim was to develop a new consultation-specific questionnaire on patient experiences. METHODS: The questionnaire was developed in Norwegian primary care in three main phases. Phase 1: focus groups with patients in order to identify important aspects of patients' experiences, and their words and language when describing such experiences. Phase 2: a questionnaire survey with 110 items including 660 patients. Extensive testing resulted in a reduction to 25 items on six dimensions. Phase 3: a questionnaire survey with 25 items including 1092 patients. Psychometric analyses and feedback from patients and physicians involved dimensionality and tests of validity and reliability. RESULTS: A final questionnaire was produced with 18 items on five dimensions: communication; emotions; short-term outcome; barriers; and relations with the auxiliary staff. The validity and reliability estimates were highly satisfactory. Three scales were skewed while two were more equally distributed. Forty-eight per cent of the patients described less than optimal communication experiences; some communication barriers were detected in 70% of the visits and less helpful experiences with the staff were reported in 55% of the visits. Twenty-four per cent of patients left with no positive feelings, and 48% scored low on the outcome scale (knowledge, perceived result). CONCLUSIONS: The patient experience questionnaire (PEQ) emphasizes what patients value the most, i.e. interaction, emotions and outcome, and may represent a valuable tool for doctors who want feedback from their patients on the function of their doctor-patient relationships.     

Making sense of ambiguity: evaluation in internal reliability and face validity of the SF 36 questionnaire in women presenting with menorrhagia.

OBJECTIVE--To determine the face validity and internal reliability of the short form 36 (SF 36) health survey questionnaire in women presenting with menorrhagia. DESIGN--Postal survey of women recruited by their general practitioners followed by interviews of a selected subsample. PATIENTS--348 women who had consulted their general practitioner with excessive menstrual bleeding and completed questionnaires after treatment. 49 women selected from this group were interviewed in depth about their health status, and requested to complete the SF 36 questionnaire. MAIN MEASURES--Subjective accounts of functioning and wellbeing as measured by the eight scales of the SF 36 questionnaire. RESULTS--Data from the postal survey indicated that the ¿general health perceptions¿ and ¿mental health¿ scales of the SF 36 questionnaire had lower internal reliability coefficients than documented elsewhere. In the follow up interviews several questions on the SF 36 questionnaire were commented on as inappropriate or difficult to answer for patients with heavy menstrual bleeding. CONCLUSIONS--Some questions on the SF 36 questionnaire were difficult to answer for this group of patients. Such problems can adversely effect the validity of the measure. It is suggested that comments of patients upon measures such as the SF 36 questionnaire could both determine the appropriateness of such measures for given studies and influence questionnaire design.
