The Influence of Outcome Expectancy and Self-Efficacy on the Behavioral Intentions of Novice Exercisers

The present study was based upon self-efficacy (SE) theory (Bandura, 1986). Its purpose was to examine whether incentives, defined as the product of outcome expectancy and outcome value, would help to predict the behavioral intentions of novice exercisers when coupled with SE expectations for a specific form of exercise. Fifty- three volunteers who were novices at weight training for exercise, participated in a 2-day learn-to-weight-train clinic offered at a university. They completed pre- and postclinic measures of SE for weight training, expectancy-value ratings of outcomes primary and secondary to 1 month's weight-training participation, and a strength- of-intention measure of multiple actions consequent to clinic participation. Results indicated that primary physical health outcomes expected of postclinic participation independently predicted the variability in pre- and postclinic future intentions beyond the variance predicted by SE. Further, incentives and SE clearly discriminated between individuals extreme in the strength of their intentions at pre- and postclinic. Discussion concerns the inclusion of measures of incentive in studies using self-efficacy theory in order to examine individuals who begin exercise and then move through various decision stages about exercise adoption and maintenance. Rather than merely assuming the influence of incentives necessary and sufficient to encourage a cognitive or behavioral impact of efficacy, arguments are made for actively examining incentive as manifested through outcome expectations.     

CHOICE-MAKING TREATMENT OF YOUNG CHILDREN'S SEVERE BEHAVIOR PROBLEMS

The choice-making behavior of 5 young children with developmental disabilities who engaged in aberrant behavior was studied within a concurrent operants framework. Experimental analyses were conducted to identify reinforcers that maintained aberrant behavior, and functional communication training packages were implemented to teach the participants to gain reinforcement using mands. Next, a choice-making analysis, in which the participants chose one of two responses (either a mand or an alternative neutral response) to obtain different durations and qualities of reinforcement, was conducted. Finally, treatment packages involving choice making via manding were implemented to decrease inappropriate behavior and to increase mands. The results extended previous applications of choice making to severe behavior disorders and across behaviors maintained by positive and negative reinforcement.     

Stress and strain in blue-collar and white-collar management staff

Previous research has demonstrated the relationship of work stress to indices of job strain, as well as underscoring the importance of moderating variables. In the present study of a mining organization it was hypothesized that personnel associated with actual mining operations would demonstrate stress-strain relationships different from those associated with administrative and staff work. Measures of stress and strain were obtained from management staff of blue-collar and white-collar groups to assess the moderating influence of collar color. Results strongly support collar color as a moderator variable. In particular, the two groups differ significantly with respect to how role conflict, job security, quantitative work load, variation in work load, and utilization of skills impact various strains. The effect of job function on stress and strain and possible practical implications of these results are discussed.     

Sex differences and sex-role stereotyping in clinical psychologists' reports: a research note

This paper presents an empirical study of sex differences and sex-role stereotyping in clinical psychologists' reports. The results of numerous analyses showed no significant evidence at any point of sex differences or sex-role stereotyping in the form or the subject matter of the clinical reports.

     

Tau-equivalence and equipercentile equating

Test scores that are not perfectly reliable cannot be strictly equated unless they are strictly parallel [Lord, 1980]. This fact implies that tau-equivalence can be lost if an equipercentile equating is applied to observed scores that are not strictly parallel. Seventy-two simulated testing conditions are produced to simulate equating tests with different difficulties and discriminations. Number-correct and trait metrics are examined. When an equipercentile equating is applied to these data, locally biased (i.e., non-tau-equivalent) results are produced for tests of unequal difficulty. Differences between the criteria of tau-equivalence and equipercentile equivalence are discussed.     

Recency effects in direct and indirect memory tasks

In three experiments, subjects learned two lists under incidental conditions and were then given either a part-word or a word (extralist associate) cue. Each cue was related to one word in each list. Half the subjects were given production instructions (an indirect memory test), and half were given cued recall instructions (a direct memory test). When the interval between List 2 and the test was shortened, recency effects were found for part-word cues for both cued recall and production instructions. Little or no recency effects were found with word cues. These results are incompatible with a simple distinction between the types of memory trace or information that are tapped by direct as opposed to indirect memory tasks. Possible causes for the recency effect and for the difference between word and part-word cues are discussed.     

Development of a structured psychiatric interview for children: Agreement between child and parent on individual symptoms

To test the reliability of children's reporting as compared with that of their mothers, a highly structured psychiatric diagnostic interview was used with 307 subjects, ages 6 through 16. Another interviewer gave each mother a similar interview about the child. Responses of each mother-child pair to 168 questions were compared using the kappa statistic. Highest agreement was found on questions concerning symptoms that are concrete, observable, severe, and unambiguous. Mothers tended to report significantly more behavioral symptoms, and children more subjective symptoms. Reasons for low kappas and asymmetrical reporting of symptoms are discussed.
