The Importance of Construct Validity in Consumer Research

Vosgerau, Scopelliti, and Huh (2020) question the construct validity of the most commonly used measures of self‐control and argue that many studies that claim to be examining self‐control may in fact be examining something else. In this comment, we generalize this argument and propose that this criticism could be leveraged against many other areas of consumer research. Indeed, many studies fail to properly establish the construct validity of their measures. Consequently, they may not be examining the construct they purport to be studying, which can lead to unreliable and conflicting findings.     

Thought-shape fusion in anorexia nervosa: an experimental investigation

Cognitive biases and cognitive distortions have been implicated as important factors in the development and maintenance of many disorders. The concept of thought-shape fusion (TSF) in eating disorders was developed by Shafran, Teachman, Kerry, and Rachman (British Journal of Clinical Psychology 38 (1999) 167) as a variant of thought-action fusion, described by Shafran, Thordarson and Rachman (Journal of Anxiety Disorders 10 (1996) 379). TSF occurs when thinking about eating certain types of food increases a person's estimate of their shape and/or weight, elicits a perception of moral wrongdoing, and/or makes the person feel fat. Shafran et al. (1999) examined both the psychometric and experimental properties of TSF in an undergraduate sample. This paper reports an extension of this work to a clinical group (N=20) of patients with anorexia nervosa. After completing a set of relevant questionnaires, participants were asked to think about a food which they considered extremely fattening. They were then asked to write out the sentence, "I am eating--.", inserting the name of the fattening food in the blank. After being asked to rate their anxiety, guilt, feelings about their weight, morality, etc., participants were given the opportunity to neutralize their statement in any way they chose. The majority of the participants neutralized in ways consistent with the findings of Shafran et al. (1999). The results are discussed in terms of cognitive-behavioural formulations of eating disorders, and of the influence of cognitive biases and cognitive distortions on the processing of information relevant to food, weight and shape in anorexia nervosa.     

Eat,drink, and be merry,for tomorrow we diet: effects of anticipated deprivation on food intake in restrained and unrestrained eaters

This study examined the effect of anticipated food deprivation on intake in restrained and unrestrained eaters. Participants were randomly assigned to a diet condition, in which they expected to diet for a week, or to a control (no-diet) condition. Immediately after being assigned to a condition, participants completed a taste-rating task in which food consumption was measured. Restrained eaters in the diet condition consumed significantly more food than did restrained eaters in the no-diet condition or unrestrained eaters in either condition. Unrestrained eaters consumed the same amount regardless of condition. These results confirm that merely planning to go on a diet can trigger overeating in restrained eaters, reflecting the dynamic connection between dieting and overeating.     

The accessibility of characters in single sentences: proper names,common nouns,and first mention

Accessibility of characters in two-character sentences (e.g., The butler helped Calvin at the wedding reception) was investigated with a probe recognition task. Probes were either the first character (e.g., butler) or the second character (e.g., Calvin) in a sentence and were designated by proper names or common nouns crossed with name or noun nonprobes. Results show that (1) probes in first position are more accessible than those in second position, but not when noun probes are paired with name nonprobes, (2) characters designated by names are generally more accessible than those designated by nouns, and (3) the first name in a sentence is more available than other characters, regardless of position. Thus, accessibility of characters in a sentence seems dependent on discourse function, with named characters seen as main characters, rather than on nondiscourse-related factors, such as temporal distinctiveness.     

Do Positive Self-Perceptions Have a “Dark Side”? Examination of the Link between Perceptual Bias and Aggression

The hypothesis that positive self-perceptions may have a dark side was investigated in the present study by examining the relationship between positively biased self-perceptions and aggression. Ratings of actual and perceived social acceptance of third-grade (n = 278), fourth-grade (n = 260), and fifth-grade (n = 321) students were compared to form a measure of perceptual bias. Peers provided nominations for overt and relational aggression. Gender differences were found for aggression (males were more overtly and relationally aggressive than females) but not perceptual bias. African-American children held more positive perceptions of their social acceptance and were perceived by peers as more aggressive than Caucasian children. Even after controlling for the effects of gender and ethnicity, more positively biased perceptions were associated with more peer nominations for overt and relational aggression. Contrary to an optimal range of bias hypothesis, even moderately positive self-perceptions were associated with elevated levels of aggression.     

Word Frequency Effects on the Processing of Subject–Verb Number Agreement

This paper examines the role of word frequency in the computation of subject–verb number agreement. Previous research in both production and comprehension has demonstrated that processing difficulties can arise in sentence structures containing a singular subject noun followed by a plural distractor noun, as in The key to the cabinets.¨ A whole sentence reading task was employed to determine whether the relative frequency with which the distractor noun appears in its singular or plural form would affect the degree of processing difficulty experienced by readers. Results suggest that the agreement process is, indeed, sensitive to this factor and this finding is compatible with activation-based accounts of the implementation of number agreement.     

Attributional Style, Self-Esteem, and Human Immunodeficiency Virus: A Test of the Hopelessness and Self-Esteem Theories of Depression

Research on the hopelessness and self-esteem theories of depression (Abramson, Metalsky, & Alloy, 1989; Metalsky, Joiner, Hardin, & Abramson, 1993) suggests that HIV-infected persons with depressotypic attributional style (AS) and low self-esteem (SE) may be at risk for onset of a syndrome referred to as hopelessness depression (HD). In a prospective study conducted to test these theories, measures of anxiety and depression, AS, and SE were administered to 85 HIV+ and 43 HIV– men; symptoms were reassessed 6 months later. Results indicated that: (1) The interaction of AS, SE, and HIV status predicted change in HD symptoms, but not overall depression or anxiety symptoms; (2) HIV+ men with depressotypic AS and high SE had increased HD symptom levels while other men with high SE had decreased HD symptom levels; (3) HD symptoms remained stable over the 6-month interval among men with low SE; and (4) High SE predicted decreases in anxiety symptoms among HIV– men, but not among HIV+ men. Contrary to the study hypothesis, these findings suggest that among individuals with life-threatening illnesses such as HIV infection, those with depressotypic AS and high SE may be at highest risk for onset of HD.     

Toward a biopsychosocial model for 21st-century genetics

Advances in genomic research are increasingly identifying genetic components in major health and mental health disorders. This article presents a Family System Genetic Illness model to address the psychosocial challenges of genomic conditions for patients and their families, and to help organize this complex biopsychosocial landscape for clinical practice and research. This model clusters genomic disorders based on key characteristics that define types of disorders with similar patterns of psychosocial demands over time. Key disease variables include the likelihood of developing a disorder based on specific genetic mutations, overall clinical severity, timing of clinical onset in the life cycle, and whether effective treatment interventions exist to alter disease onset and/or progression. For disorders in which carrier, predictive, or presymptomatic testing is available, core nonsymptomatic time phases with salient developmental challenges are described pre- and post-testing, including a long-term adaptation phase. The FSGI model builds on Rolland's Family System Illness model, which identifies psychosocial types and phases of chronic disorders after clinical onset. The FSGI model is designed to be flexible and responsive to future discoveries in genomic research. Its utility is discussed for research, preventive screening, family assessment, treatment planning, and service delivery in a wide range of healthcare settings.
