Temporal stability of behavioural intention as a moderator of intention–health behaviour relationships

Seven prospective studies of health behaviours containing eight prospective datasets testing the moderating role of intention stability on intention–behaviour and past behaviour–behaviour relationships were examined within the context of the Theory of Planned Behaviour. The measure of intention stability was based on lack of change in intentions between the two measurement time points. Across different behaviours, samples and time frames more stable intentions were associated with intentions at time 1 that were stronger predictors of behaviour at time 2. Intention stability did not consistently moderate the past behaviour–behaviour relationship. Across studies the frequency-weighted mean correlation between intentions and behaviour was substantially greater for stable (r ₊?=?0.60) compared to unstable (r ₊?=?0.27) intentions (Z _difference?=?6.65, p?<?0.001). The past behaviour–behaviour correlation was also stronger for stable (r ₊?=?0.50, p?<?0.001) compared to unstable (r₊ ?=?0.34, p?<?0.001) intentions (Z _difference?=?3.12, p?<?0.01). Perceived behavioural control was the variable most strongly related to stable intentions. Implications for understanding the role of health cognitions in the performance of health behaviour are discussed.     

Question–behaviour effect: A randomised controlled trial of asking intention in the interrogative or declarative form

Objective: This study investigated the question–behaviour effect of measuring intention in the interrogative or declarative form combined or not with a measure of moral norm.

Design: A sample of 762 participants was randomised according to a 2?×?2 factorial design.

Main outcome measures: Cognitions were assessed at the baseline, and physical activity behaviour was self-reported three weeks later. Results: At baseline, there were no significant differences on the studied variables. An ANOVA showed a significant interaction effect between the two experimental conditions (p?=?0.04). Post-hoc contrast analyses showed that the interrogative intention-only condition significantly differed from the declarative intention-only (d?=?0.21, p?=?0.03) and interrogative intention?+?moral norm (d?=?0.22, p?=?0.03) conditions.

Conclusion: Results suggest that self-posed questions about a future action increases the likelihood of doing it when these questions are not accompanied by measures of moral norm. This provides support for using introspective self-talk to favour the adoption of behaviour.     

Understanding physical activity behavior and cognitions in pregnant women: An application of self-determination theory

ObjectivesAlthough regular exercise during pregnancy is linked with improved health outcomes for both mother and foetus, many pregnant women are inactive. The purpose of this study was to use organismic integration theory (OIT) as the guiding theory for examining the relationship between autonomous and controlled motives for (a) exercise behavior reported over a typical week and barriers to exercise and (b) exercise and stage of pregnancy (i.e., trimester).DesignCross-sectional.MethodsParticipants (N = 75) were pregnant women who completed a multi-component, Internet-based survey.ResultsMultiple regression analyses showed that identified regulation predicted greater exercise behavior and fewer exercise barriers, irrespective of trimester. Further analyses indicated that women in the first trimester reported significantly higher identified regulation compared to women in either second or third trimesters.ConclusionsOverall, these findings reinforce the importance of distinguishing controlled from autonomous exercise motives and demonstrate the tenability of OIT for enhancing our understanding of exercise behavior and barriers during pregnancy.     

Work and immigrants: An analysis of employment activity in the first ten years of establishment in the Montreal area

The Quebec labour market of the last two decades has undergone profound changes due to progress in information technology and market globalization. This new context has generated new forms of work which have been termed” non-standard work”. Since the early eighties, the number of such positions has been growing significantly. Often associated with precarious employment activity, the phenomenon of non-standard work has raised a fundamental question: are these positions stable? This is the main question that we wish to investigate from the perspective of new immigrants: do new immigrants achieve stability in the labour market upon arrival in Quebec? In a society that has, quite often for demographic and economic reasons, welcomed an average of 35,000 newcomers every year since the early 90s, the success (or failure) of economic integration rests in part on immigrants’ capacity to participate in the labour market and remain employed. Our analysis is based on a longitudinal survey that describes the biographical trajectories of the Settlement of New Immigrants (SNI). This survey describes the main attempts of 1,000 immigrants’ to establish themselves over a period of 10 years in the greater Montreal area. This research mainly shows that continuous sequences of employment are growing overtime, thus ensuring new immigrants greater stability in the labour market. On the other hand, results suggest that racial discrimination modulates labour market participation, in particular for natives of North Africa and the Middle East.     

Backward recognition masking as a general type of interference in needed poststimulus processing

Auditory backward recognition masking (ABRM) has been argued to reflect interference in the storage and/or processing of a short-lived sensory form of information and has been viewed as a relatively invariant attribute of auditory pitch processing for very brief stimuli that are minimally separated in frequency (DeltaF). In contrast, the present study demonstrates that ABRM reflects interference with several basic principles of auditory processing. Measured in terms of target tone duration, rather than DeltaF, ABRM is demonstrated for target stimuli representing the interval of a musical fifth and masker-target stimulus intervals of a musical third, with thresholds ranging from approximately 22 to 55 msec and psychometric functions that are indicative of more than one contributing factor. On the basis of common underlying principles, the possibility that the threshold for the identification of temporal order of onset reflects ABRM and possible implications for the perception of complex stimuli, including speech, are discussed.     

Choosing a Place of Death: The Influence of Pain and of Attitude Toward Death1

This experimental study sought to verify if factors like pain or attitude toward death can determine the choice of a place of death. Using a questionnaire developed from Triandis’(1980) theory, the influence of pain on the intention of choosing a place of death was measured among 138 respondents. “Attitude toward death,” used as a control variable, was measured by means of the Death Attitude Profile. Variance analyses (p < .008) demonstrated the influence of pain on intention of choosing a place of death and on the cognitive component. Linear regression (p .002) highlighted 2 determinants of intention of choosing a place of death: moral norm and social role. As for attitude toward death, it seems to have no influence on the choice of a place of death.     

Prediction of Needle Sharing Among Injection Drug Users1

The aim of the present study was to identify the psychosocial factors associated with the intention and behavior of not sharing used needles and syringes among 459 intravenous drug users (IDUs). The intention to not share used needles was positively associated with personal normative beliefs and self‐efficacy; it was negatively related to the proportion of injections with lending used needles and borrowing syringes from sexual partners. Borrowing used needles was negatively associated with intention whereas loaning syringes was positively related to a negative HIV test result. These results suggest that it is only when a direct personal exposure to HIV infection is possible (borrowing) that intention not to borrow is highlighted. Moreover, being HIV positive appears to reduce loaning used syringes.     

Factors Explaining the Intention to Use Condoms Among Injecting Drug Users Participating in a Needle‐Exchange Program1

This study identified the psychosocial factors related to condom‐use intention, based on Triandis’ (1980) theory of interpersonal behavior, among 261 injection drug users participating in a needle‐exchange program. With regular partners (n= 139), condom‐use intention was explained by normative beliefs, self‐efficacy, length of relationship with last regular sexual partner, and taking oral contraceptives. Condom‐use intention with casual partners (n= 157) was also associated with self‐efficacy and normative beliefs, on top of cognitive dimension with attitudes and lending used needles. Neither the perception of being HIV‐positive, nor the habit of using a condom was associated with intention. It is thus suggested that interventions aimed at promoting condom use among this clientele be oriented toward the reinforcement of personal convictions as well as toward the development of competencies needed to overcome obstacles, since both relate to the intention to adopt this behavior.     

Time-shrinking: A discontinuity in the perception of auditory temporal patterns

Recent research at our laboratories in the field of human auditory time perception revealed that the duration of short empty time intervals (<～200 msec) is considerably underestimated if they are immediately preceded by shorter time intervals. Within a certain range, the amount of subjective time shrinking is a monotonous function of the preceding time interval: the shorter it is, the more it shrinks its successor. In the present study, the preceding interval was kept constant at 50 msec, and the following interval for which the duration had to be judged, varied from 40 to 280 msec. The results showed that at up to 100 msec, the perceived duration increased to a much lesser extent than did the objective duration. Beyond 120 msec, the perceived duration quickly increased and reached a veridical value at 160 msec. Such a sudden change of perceived duration in a temporal pattern in which the objective duration varies gradually indicates a typical example of categorical perception. We suggest that such a categorization of the time dimension might be a clue for processes of speech and music perception.
