Self-determination and functional persuasion to encourage physical activity

This research advances a novel approach to promoting physical activity, based on the principle of functional matching in persuasion, and the self-concordance (SC) of people's motivations for physical activity. We propose that SC establishes a positive or negative orientation toward the challenge inherent in physical activity, and that the maximum yield of participation will be achieved by communications that appeal to each orientation. In two studies, we compared how messages emphasizing challenge versus available social support would influence recipients’ self-reported practices of physical activity and attitudes toward a physical activity setting. As hypothesized, these messages had differential effects for recipients whose pursuit of physical activity varied in SC, such that favorable outcomes were more reliably associated with challenge-oriented messages among respondents higher in SC versus support-oriented messages among respondents lower in SC. The findings suggest the merits of using self-regulatory, compared with object- or personality-based, constructs and measures to indicate psychological functions of ongoing health-related behaviors.     

The relationship between mental vitality and cardiovascular health

Past measurement of vitality has included both emotional and physical components. Since aspects of physical vitality such as fatigue can be indicative of physical illness, the usefulness of existing measures of vitality to predict health is limited. This research was designed to examine the psychometric properties of a new Mental Vitality Scale and to test its associations with measures of cardiovascular health over the course of 2 years. The measure of mental vitality was administered in a two-part study using three different samples. In part 1, the reliability and validity of the scale was assessed with a student and a clinic sample. In part 2, medical data on mental and physical health were abstracted over a two-year period from 1041 patient records from a multi-specialty medical practice, and mental vitality assessed through a mailed questionnaire. The findings indicate that the Mental Vitality Scale is a valid and reliable questionnaire for measuring this construct. Mental vitality was also associated with reduced odds of several cardiovascular outcomes and prospective analyses suggest that mental vitality may serve a protective function in the development of cardiovascular disease. The results lend support for the importance of mental vitality as a construct that may be relevant for considering resilience in relation to cardiovascular disease.     

Being and feeling liked by others: How social inclusion impacts health

This study examined the effects of perceived and actual social inclusion on health across and within individuals from a network perspective. During the first semester, 75 freshmen students provided bi-weekly ratings on their perceived social inclusion and health. To capture actual social inclusion, each student nominated liked and disliked fellow students. Perceived social inclusion mediated the effect of actual social inclusion on health. Specifically, students with more ‘likes’ perceived more social inclusion and those with higher perceived inclusion reported a better health status (between-person effect). In addition, at time points, when students received more ‘likes’ they also perceived more social inclusion. They reported better health at times when they felt more included (within-person effect). Thus, the perception of social inclusion is rooted in reality and actual social inclusion has an impact on health when passing the filter of perception.     

Risk drinking and contraception effectiveness among college women

Risk drinking, especially binge drinking, and unprotected sex may co-occur in college women and increase the risks of STI exposure and pregnancy, but the relationships among these behaviors are incompletely understood. A survey was administered to 2012 women of ages 18–24 enrolled in a public urban university. One-quarter of the college women (23%) drank eight or more drinks per week on average, and 63% binged in the past 90 days, with 64% meeting criteria for risk drinking. Nearly all sexually active women used some form of contraception (94%), but 18% used their method ineffectively and were potentially at risk for pregnancy. Forty-four percent were potentially at risk for STIs due to ineffective or absent condom usage. Ineffective contraception odds were increased by the use of barrier methods of contraception, reliance on a partner's decision to use contraception, and risk drinking, but were decreased by the use of barrier with hormonal contraception, being White, and later age to initiate contraception. In contrast, ineffective condom use was increased by reliance on a partner's decision to use condoms, the use of condoms for STI prevention only, and by risk drinking. Thirteen percent of university women were risk drinkers and using ineffective contraception, and 31% were risk drinkers and failing to use condoms consistently. Risk drinking is related to ineffective contraception and condom use. Colleges should promote effective contraception and condom use for STI prevention and consider coordinating their programs to reduce drinking with programs for reproductive health. Emphasizing the use of condoms for both pregnancy prevention and STI prevention may maximize women's interest in using them.     

Lay concepts of health and illness from a developmental perspective

Abstract

The concepts of children, adolescents and their mothers with regard to different aspects of health and illness in general and five specific diseases were explored in this study. An exploration with fully standardised questions and open answers was subjected to a content analysis. A reliable rating system was developed to score the sophistication of the answers. The study included 99 Ss of the age groups 5, 8, 12 and 16 years, as well as 48 mothers of the children. Many children and adolescents were able to define health positively (well-being) and not merely as the absence of illness. The definition of illness in general was frequently composed of somatic symptoms and disorders, feeling poorly and things one would like to accomplish but can't. The causality explanations of illness in general were dominated by contagion. The concepts of the older children and the mothers were richer, more elaborated, less concrete and less action-oriented than those of the younger children. However, abstract formulations and complex aspects of illness were very rarely expressed. In addition, concepts regarding the characteristics (definition, symptoms, causality, treatment and prevention) of five diseases (cold, measles, heart infarction, cancer and AIDS) were measured. The pattern of results was strongly influenced by age. By and large, the development of most disease concepts was linear with significant differences between age groups. Conversely, within a given age group, significant differences were found in the cognitive level of disease characteristics, either with respect to the same disease or between different diseases (“horizontal shifts”).     

The health benefits of writing about positive experiences: The role of broadened cognition

This study tested the potential to elicit a broadened attentional focus through writing about a positive life experience and to derive health benefits from such writing. Participants (n = 38) wrote for 20 min each day for 3 consecutive days about either a positive life experience or a control topic. Writing about positive experiences led to improved physical health (measured 4–6 weeks after writing) compared to control and higher levels of global cognitive focus after writing mediated this effect. Notably, while the positive writing condition was more broadened than control, positive affect was not responsible for this difference. Implications for disclosive writing and the broaden and build model are discussed.     

Socio-economic health inequalities: Their origins and implications

Abstract

Evidence attests to substantial variations in health contingent on socioeconomic position. It is argued that these effects cannot be dismissed as artefact nor can they be explained, in the main, by either social selection or an unequal distribution of accepted behavioural risk factors among different social groups. The most likely explanation would seem to be social causation. However, it is continuing social and material inequality that appears most implicated; accounts which locate the effects in childhood social and material causes are far less compelling. The persistence of socioeconomic health differentials into the materially better-off social strata and the possible determining role of relative as well as absolute living standards suggest that psychological, in addition to material, variables are likely to be involved. Isolating the key psychological variables and identifying the nature of their influences will not be easy tasks, although social relations, psychological stress, uplifts, and control have emerged as possible candidates. However, psychological mediators of this sort most probably constitute surface rather than basic causes. Socio-economic inequality, it is contended, remains the basic cause, and, as such, the proper target for intervention. Psychological interventions are unlikely to yield much in the way of dividends in this context and indeed could inadvertently contribute to victim blaming.     

One ‘knows’: self-rated health and telomere length among ex-prisoners of war

Abstract

Objective: Ill-health and early mortality are amongst the most significant ramifications of trauma. Furthermore, trauma alters the subjective perception and experience of the body. The aim of this study is to examine the extent to which deteriorations in perceived health among traumatised individuals are associated with cellular health as manifested in telomere length.

Methods: Specifically, 88 former prisoners of war (ex-POWs) evaluated their health (self-rated health; SRH) at 18 (T1), 35 (T2) and 42 (T3) years after the war, and were assessed for telomere length at T3. Health behaviour, BMI, morbidity and PTSD were also examined at T3.

Results: The findings demonstrated that SRH was cross-sectionally correlated with telomere length. Furthermore, a significant sequential indirect effect was found, in which worse SRH in T1 was associated with shorter telomere length at T3, through worse SRH at T2 and at T3.

Conclusions: These findings demonstrate that long-term deteriorations in the subjective evaluations of health are implicated in actual cellular health among individuals exposed to trauma.     

Identity,coping style,and health behaviour among first generation Irish immigrants in England

Abstract

Berry's (1997) framework for acculturation research was used to explore the relationship between identity and health among Irish immigrants in England. One hundred and twelve first generation Irish immigrants completed questionnaire measures of ethnic identity, opportunities for identity expression, generalised coping style, and health behaviour. Significant, though small, positive correlations were observed between identity and health behaviour as predicted. Regression analyses and path analysis were used to present a model of the link between variables. Of particular note were the contrasting ways in which the two dimensions of identity were associated with health behaviour. Participants who positively evaluated their ethnic origins reported engaging in healthier behaviour and adopting more beneficial coping strategies when faced with day-to-day stresses and problems. Participants who reported their ethnic origin as more central to their overall identity were also more likely to adopt beneficial coping strategies. Concomitantly, however, they had fewer than desired opportunities for expressing their ethnic identity which was, in turn, associated with less beneficial coping and health behaviour. In looking for ways to tackle the well-documented health problems of both first and second generation Irish in England, the results suggest that encouragement to feel more positive about their ethnic identity might result in greater usage of behavioural approach coping and, relatedly, to improved health behaviour.     

Reducing demand for ineffective health remedies: overcoming the illusion of causality

Abstract

Objective: We tested a novel intervention for reducing demand for ineffective health remedies. The intervention aimed to empower participants to overcome the illusion of causality, which otherwise drives erroneous perceptions regarding remedy efficacy.

Design: A laboratory experiment adopted a between-participants design with six conditions that varied the amount of information available to participants (N?=?245). The control condition received a basic refutation of multivitamin efficacy, whereas the principal intervention condition received a full contingency table specifying the number of people reporting a benefit vs. no benefit from both the product and placebo, plus an alternate causal explanation for inefficacy over placebo.

Main outcome measures: We measured participants’ willingness to pay (WTP) for multivitamin products using two incentivized experimental auctions. General attitudes towards health supplements were assessed as a moderator of WTP. We tested generalisation using ratings of the importance of clinical-trial results for making future health purchases.

Results: Our principal intervention significantly reduced participants’ WTP for multivitamins (by 23%) and increased their recognition of the importance of clinical-trial results.

Conclusion: We found evidence that communicating a simplified full-contingency table and an alternate causal explanation may help reduce demand for ineffective health remedies by countering the illusion of causality.
