Meaning behind measurement : self-comparisons affect responses to health related quality of life questionnaires

Purpose The subjective nature of quality of life is particularly pertinent to the domain of health-related quality of life (HRQOL) research. The extent to which participants’ responses are affected by subjective information and personal reference frames is unknown. This study investigated how an elderly population living with a chronic metabolic bone disorder evaluated self-reported quality of life. Methods Participants (n = 1,331) in a multi-centre randomised controlled trial for the treatment of Paget’s disease completed annual HRQOL questionnaires, including the SF-36, EQ-5D and HAQ. Supplementary questions were added to reveal implicit reference frames used when making HRQOL evaluations. Twenty-one participants (11 male, 10 female, aged 59–91 years) were interviewed retrospectively about their responses to the supplementary questions, using cognitive interviewing techniques and semi-structured topic guides. Results The interviews revealed that participants used complex and interconnected reference frames to promote response shift when making quality of life evaluations. The choice of reference frame often reflected external factors unrelated to individual health. Many participants also stated that they were unclear whether to report general or disease-related HRQOL. Conclusions It is important, especially in clinical trials, to provide instructions clarifying whether ‘quality of life’ refers to disease-related HRQOL. Information on selfcomparison reference frames is necessary for the interpretation of responses to questions about HRQOL.The Chief Scientist Office of the Scottish Government Health Directorates, The PRISM funding bodies (the Arthritis Research Campaign, the National Association for the Relief of Paget’s disease and the Alliance for Better Bone Health)Peer reviewedAuthor final versio

Effects of Attractiveness and Social Status on Dating Desire in Heterosexual Adolescents: An Experimental Study

The present study examined to what extent adolescent dating desire is based on attractiveness and social status of a potential short-term partner. Further, we tested whether self-perceived mate value moderated the relationship between dating desire and attractiveness of a potential partner. Data were used from a sample of 1,913 adolescents aged 13–18. Participants rated the importance of various characteristics of a potential partner and also participated in an experimental vignette study in which dating desire was measured with either low or high attractive potential partners having either a high or low social status. The results showed that boys rated attractiveness as more important than girls, while social status was rated as relatively unimportant by both sexes. In addition, in the experimental vignette study, it was found that attractiveness was the primary factor for boys’ dating desire. Only when a potential partner was attractive, social status became important for boys’ dating desire. For girls, on the other hand, it appeared that both attractiveness and social status of a potential partner were important for their dating desire. Finally, boys and girls who perceived themselves as having a high mate value showed more dating desire toward an attractive potential partner compared to adolescents who perceived themselves as having a low mate value. The present results extend previous research by showing that attractiveness of a potential partner is important to both adolescent boys and girls, but social status does not strongly affect dating desire during this particular age period

Disgust trumps lust:women’s disgust and attraction towards men is unaffected by sexual arousal

Mating is a double-edged sword. It can have great adaptive benefits, but also high costs, depending on the mate. Disgust is an avoidance reaction that serves the function of discouraging costly mating decisions, for example if the risk of pathogen transmission is high. It should, however, be temporarily inhibited in order to enable potentially adaptive mating. We therefore tested the hypothesis that sexual arousal inhibits disgust if a partner is attractive, but not if he is unattractive or shows signs of disease. In an online experiment, women rated their disgust towards anticipated behaviors with men depicted on photographs. Participants did so in a sexually aroused state and in a control state. The faces varied in attractiveness and the presence of disease cues (blemishes). We found that disease cues and attractiveness, but not sexual arousal, influenced disgust. The results suggest that women feel disgust at sexual contact with unattractive or diseased men independently of their sexual arousal

Life History of Female Preferences for Male Faces: A Comparison of Pubescent Girls, Nonpregnant and Pregnant Young Women, and Middle-aged Women

Although scientific interest in facial attractiveness has developed substantially in recent years, few studies have contributed to our understanding of the ontogeny of facial preferences. In this study, attractiveness of 30 male faces was evaluated by four female groups: girls at puberty, nonpregnant and pregnant young women, and middle-aged women. The main findings are as follows: (1) Preference for sexy-looking faces was strongest in young, nonpregnant women. (2) Biologically more mature girls displayed more adultlike preferences. (3) The intragroup consistency for postmenopausal women was relatively low. (4) In terms of the preference pattern, pregnant women were more similar to perimenopausal women than they were to their nonpregnant peers. (5) Preference for youthful appearance decreased with the age of the women. I argue that the life history of female preferences for male faces is, to a large extent, hormone-driven and underpinned by a set of evolutionary adaptations

Infidelity-Revealing Snapchat Messages Arouse Different Levels of Jealousy Depending on Sex, Type of Message and Identity of the Opposite Sex Rival

Research highlighting sex-differentiated jealousy resulting from imagined scenarios has now been reaffirmed when the infidelity-revealing message is discovered on a social media platform. Participants in the current study were presented with both sexually and emotionally charged infidelity-revealing scenarios featuring a same-sex sibling, a friend and a stranger in the format of a ‘Snapchat’ message. Men indicated significantly higher jealousy to sexual as opposed to emotional messages with the reverse pattern evident in women. Sex differences were also evident in the extent of jealousy elicited by ‘third-party’ identity. Women were significantly more jealous when the imagined infidelity occurred between their sister compared to both a best friend and a stranger with males showing significantly lower jealousy directed towards their brother compared to a stranger. These findings are supportive not only of a parental investment (PI) interpretation of sex differences in jealousy but also an interpretation consistent with aspects of inclusive fitness theory

Social comparison and optimism about one's relational future: order effects in social judgment

This research tested the hypothesis that when individuals first answer a question about relative evaluation, i.e. the degree in which they feel they are better or worse off than comparison others and next a question about general evaluation, i.e. the general judgment of one's situation or one's characteristics, the correlations between both variables will be higher than when the order of the questions is reversed. In the first case individuals will use social comparison information as a reference point for making a judgement of their situation, whereas general evaluations not preceded by relative evaluations may be based on a variety of factors. The content of the questions concerned optimism with respect to one's own prospects concerning intimate relationships, i.e. the perceived chances of having a happy intimate relationship in the future, and the perceived chance of not becoming involved in a divorce. The results of two studies-a questionnaire study among students (n = 274), and a computer administered survey among single adults (n = 275)-confirmed the predictions. (C) 1998 John Wiley & Sons, Ltd
