Family process in health research: extending a family typology to a new cultural context

To describe family context in health research, the authors tested a typology of families developed in California with a sample of families in Quebec, Canada. Family scales from the California study were submitted to focus groups, translated, and standardized on a sample of 209 parents. A panel of experts then revised the scales to make them relevant to Quebec families and to health promotion. Data from the new and revised scales were collected on 509 Quebec couples (1,018 spouses) and were clustered separately by gender, using K means. The procedure classified all respondents into family types that paralleled the original typology. Discriminant analyses indicated that family profile variables significantly distinguished family types. Comparisons with family, stress, and health variables further differentiated among the types and expanded their meaning. The study demonstrates a method for redefining and extending family data in health research with different cultural groups.

A global measure of access to mental health services for a managed care environment

The growing influence of managed care in mental health services has raised important questions about access to services. This article introduces and demonstrates a global measure of access that is based on the relationship between service utilization and the need for services. This measure has become practical because of recent advances in measurement technology that provide more valid and reliable estimates of the prevalence of mental illness in general populations and of the number of people who receive mental health services across service sectors. The methodology is used to produce a report card type profile of access to inpatient mental health services (in state, general, private, and veterans hospitals) by residents of one state. This global measure can provide a powerful and efficient tool for monitoring and comparing the impact of managed care plans on access to mental health services.

A naturalistic study of the impact of acute physical activity on feeling states and affect in women

This field study used experience sampling procedures to examine the relationship of feeling states and affect to acute bouts of physical activity in women. Participants (N = 86) completed brief affect and feeling state measures (a) in response to random stratified pager tones and (b) before and after acute bouts of vigorous physical activity for 6 weeks. Analysis of averaged difference scores revealed that acute vigorous physical activity was associated with significant improvements in affect and feeling states, particularly in feelings of revitalization. Moreover, within-subject analyses indicated that the effects were moderated by preactivity scores, with the greatest improvements seen when women felt worst before activity.

Prevalence of stages of change for physical activity in rural, suburban and inner-city communities

This study documented the differing prevalence rates for stages of change for physical activity across rural, suburban and inner city communities using survey methods and controlling for education, gender and disease status. Respondents (n = 4768) were participants in the baseline survey for the evaluation of the Québec Heart Health Demonstration Project, a health promotion program implemented in various communities throughout the province of Québec. A total of 2639 female and 2087 male parents answered a questionnaire they received from their grade 4 to grade 6 children. The questionnaire dealt with demographic information, health-related behaviors, and intentions for these behaviors. The response rates were 90%, 77% and 70% in the rural, suburban and inner city communities respectively. Results showed that prevalence rates differed significantly between communities with rural communities having the highest rates of readiness for physical activity in comparison to suburban and inner city communities. These findings suggest that above and beyond individual difference variables, structural components such as type of community are related to people's readiness for physical activity involvement.

Drug and alcohol use by Canadian university athletes: a national survey

To gauge the extent of drug and alcohol use in Canadian university athletes, we estimated the proportion of Canadian university athletes using social and/or ergogenic drugs through survey methods. A secondary purpose was to examine athletes' perceptions of the value of drug testing and drug education programs. Using a stratified random sampling procedure, 754 student athletes were surveyed in eight different sports from eight universities across Canada. Results showed that 17.7 percent of athletes have used major pain medications over the past twelve months, 3 percent reported use of weight loss products, 0.9 percent reported anabolic steroid use, 16.6 percent reported use of smokeless tobacco products, 94.1 percent reported use of alcohol, 65.2 percent reported use of caffeine products, 0.7 percent reported use of amphetamines, 1.0 percent reported use of barbiturates, 19.8 percent reported use of marijuana or hashish, 5.9 percent reported use of psychedelics and 0.8 percent reported use of cocaine/crack.

Effects of baseline responses, in-task feelings, and duration of activity on exercise-induced feeling states in women

This study investigated the hypothesis that the effects of acute aerobic exercise on feeling states may be influenced by the objective dose of activity, subjective responses during exercise, and preexisting levels of feeling states. College-age women (N = 80) completed baseline measures and were then randomly assigned to 1 of 4 conditions: attention control for 10 min, or exercise for 10 min, 25 min, or 40 min. Levels of exertion and affect were assessed during exercise, and posttesting occurred 20 min following activity. Exercise enhanced revitalization in comparison with the control condition; however, this effect occurred only for participants scoring low to moderate on the pretest. In addition, in-task feeling states predicted postexercise revitalization even after we controlled for the treatment, the pretest, and the Pretest x Treatment interaction.

Mental challenge elicits "additional" increases in heart rate during low and moderate intensity cycling

The combined effects of exercise and mental challenge on heart rate (HR) and T-wave amplitude (TWA) were studied. Twenty male students cycled at low (40% of their relative maximal HR reserve (MHRR), for 15 min) and medium (60% MHRR, for 10 min) intensity exercise workloads. Subjects performed a series of mental arithmetic problems for one minute each time: two min before cycling, 10 min into low intensity cycling, 10 min into medium intensity cycling, and two and 20 min, respectively, after cycling. During both exercise workloads, the mental arithmetic elicited significant additional increases in HR. Although TWA decreased in response to mental arithmetic at rest, no changes in TWA were observed in response to mental task during exercise. However, TWA increased significantly following the mental challenge. These results suggest that even a mild mental challenge is capable of inducing further changes in the autonomic response during low and moderate exercise.

Psychophysiological profiles in response to various challenges during recovery from acute aerobic exercise

Cardiovascular and sympathetic profiles in response to a series of physical and mental challenges were examined during recovery from an acute bout of aerobic exercise performed at 60% VO2,max for 30 min. 9 healthy men were tested on two occasions, once under an experimental (exercise) and once under a control (video watching) condition, in a counter-balanced order, one week apart. Although no differences in blood pressure were found in the two conditions, heart rate and plasma catecholamine concentrations were higher in the exercise than in the control session. These findings were partly attributed to elevated physiological levels 'carried over' from exercise. State anxiety and anger-hostility, however, were lower in the post-experimental period than in the pre-experimental period. The results are discussed in terms of their relevance to exercise and stress psychophysiology.

Mathematical performance before, during, and following cycling at workloads of low and moderate intensity

Mental arithmetic performance before, during, and following low (40% maximal heart-rate reserve; approximately 90 watts exercise for 15 min.) and moderate (60% maximal heart-rate reserve; approximately 150 watts exercise for 10 min.) intensity cycling by 20 male students (M age = 28.1 yr.) was studied. Subjects were grouped, by using a median-split on their total mathematical performance scores, into a group of 10 low in arithmetic skill and a group of 10 high in arithmetic skill. The numbers and percentages of right answers to 1-min. mathematical problem-sets of either group were not different in the various conditions, suggesting that 25 min. of progressive cycling exercise did not influence mathematical problem-solving efficacy.

[The effects of positive, negative and neutral self-talk on motor performance]

The purpose of this study was to examine the influence of self-talk on motor performance. Forty-six (46) male and female college students from the Ivory Coast were randomly assigned to two experimental groups (N = 15 for each) and one control group (N = 16). All subjects completed 5 blocs of 10 trials of a dart throw on a 45-cm by 45-cm target. The distance from the center of the target was recorded by measuring the distance along the x and y axes. Subjects in one experimental group (VP) were asked to repeat aloud positive verbalizations in between blocs of trials, while subjects in the other experimental group (VN) repeated aloud negative verbalizations in between blocs of trials. The control group (T) rested between trials. Results indicated that the angular errors in the VP group decreased faster than those of the T group, that the performance of the VN group did not improve significantly, and that the rate of angular error in the VN group was higher than that of the T and VP groups.

Reactivity to written mental arithmetic: effects of exercise lay-off and habituation

The present study examined (i) the effects of exercise lay-off on heart rate (HR) and subjective response to mental stress in 24 individuals highly committed to exercise, and (ii) psychophysiological reactivity to a challenging written mental arithmetic with subjectively controlled difficulty level. Subjects were tested on two occasions one week apart. Exercise withdrawal did not influence psychophysiological stress response. Second exposure to the mental arithmetic resulted in significantly lower HR response, due to habituation; higher pretask resting HR, due to anticipation of performance; and later onset in HR recovery. No changes in task performance and subjective measures were observed from session one to session two, indicating that habituation is rather a physiological than behavioral phenomenon. While these findings do not strengthen the link between exercise and stress response, they demonstrate the significant mediatory roles of habituation and anticipation in laboratory studies employing a test-retest design.

An experiential perspective on the motivational features of exercise and lifestyle

The purpose of this study was to describe the cognitive, emotional and behavioral concomitants of direction, intensity and persistence for exercise in individuals displaying different levels of exercise involvement. In order to attain this goal, 78 one-hour interviews were conducted with individuals who were either autonomous exercisers, fitness program enrollees, fitness program dropouts or sedentary individuals. Subjects were asked to describe their thoughts, feelings and behaviours, before, during and after a workout, and trained interviewers used probes to further tease out aspects of direction, intensity and persistence. Findings were content-analyzed to detect significant trends. Results revealed that autonomous exercisers differed from individuals with less active lifestyles in several ways: participation motives were geared mainly toward fitness-health; the aspect they enjoyed the most about their participation was the task itself; they did not need to do any planning to ensure that they regularly attended their workouts; they expended a moderately high amount of effort and intensity in pursuing their exercise; they conceded that sometimes they missed workouts simply out of fatigue and that they felt that something was missing in their life when they did not exercise. By contrast, other types of exercisers displayed different profiles. These findings replicate and extend data available in the literature and thus support the viability of qualitatively conceptualizing and assessing motivation in exercise settings.
