Time to update our suggestibility scales

Oakley and colleagues (2021) suggest that a classic scale – HGSHS:A, aiming to measure hypnotic suggestibility – can be used to measure direct verbal suggestibility (DVS). According to the authors, DVS is a trait that can be measured both with and without hypnosis. I find this initiative highly welcome. However, I wish to give several examples why it is time to develop entirely new scales instead. Rather than trying to explain more phenomena with a single scale or concept, researchers should take a cue from research that points to a far more nuanced picture of suggestibility than a construct like DVS allows. There may be no single, unified phenomenon that can be measured with a single scale. The old, time-tested scales should be treated neither as sacred nor final. They require up-to-date, critical analysis of what exactly they measure, with an eye to how they can be further improved.     

Discrete response patterns in the upper range of hypnotic suggestibility: A latent profile analysis

High hypnotic suggestibility is a heterogeneous condition and there is accumulating evidence that highly suggestible individuals may be comprised of discrete subtypes with dissimilar cognitive and phenomenological profiles. This study applied latent profile analysis to response patterns on a diverse battery of difficult hypnotic suggestions in a sample of individuals in the upper range of hypnotic suggestibility. Comparisons among models indicated that a four-class model was optimal. One class was comprised of very highly suggestible (virtuoso) participants, two classes included highly suggestible participants who were alternately more responsive to inhibitory cognitive suggestions or posthypnotic amnesia suggestions, and the fourth class consisted primarily of medium suggestible participants. These results indicate that there are discrete response profiles in high hypnotic suggestibility. They further provide a number of insights regarding the optimization of hypnotic suggestibility measurement and have implications for the instrumental use of hypnosis for the modeling of different psychological conditions.     

Measurement and correlates of sport-specific cognitive and somatic trait anxiety: The sport anxiety scale

Abstract

Previous research indicates the viability of a distinction between cognitive and somatic components of the anxiety response, and multidimensional anxiety scales have proven useful in relating cognitive and somatic anxiety to behavioral outcomes. This article describes the development and validation of a sport-specific measure of cognitive and somatic trait anxiety. The Sport Anxiety Scale measures individual differences in Somatic Anxiety and in two classes of cognitive anxiety, Worry and Concentration Disruption. Both exploratory and confirmatory factor analyses supported these dimensions in several different athlete samples. Psychometric properties of the Sport Anxiety Scale are described, as are its relations with other psychological measures and with precompetition affective state measures. In the last of the four studies reported, scores on the Concentration Disruption scale were negatively related to the performance of college football players over the course of a season. The studies suggest that the Sport Anxiety Scale may be useful in defining sport-related anxiety more sharply and assessing how the cognitive and somatic anxiety components relate to performance and other outcome measures in sport.     

Can expectation enhance response to suggestion? De-automatization illuminates a conundrum

Disparate theoretical viewpoints construe hypnotic suggestibility either as a stable trait, largely determined by underlying cognitive aptitude, or as a flexible skill amenable to attitudinal factors including beliefs and expectations. Circumscribed findings support both views. The present study attempted to consolidate these orthogonal perspectives through the lens of expectancy modification. We surreptitiously controlled light and sound stimuli to convince participants that they were responding strongly to hypnotic suggestions for visual and auditory hallucinations. Extending our previous findings, we indexed hypnotic suggestibility by de-automatizing an involuntary audiovisual phenomenon-the McGurk effect. Here we show that, regardless of expectancy modification, the experimental procedure led to heightened expectations concerning future hypnotic response. We found little effect of expectation, however, on actual response to suggestion. Our findings intimate that, at least in the present experimental context, expectation hardly correlates with--and is unlikely to be a primary determinant of--high hypnotic suggestibility.     

The Perfectionism Cognitions Inventory: Psychometric Properties and Associations with Distress and Deficits in Cognitive Self-management

Two studies were conducted to examine the psychometric properties and correlates of the Perfectionism Cognitions Inventory (PCI) when administered to clinical samples. The PCI is a 25-item measure of automatic thoughts with themes involving perfectionism and beliefs that perfection should be attained. Analyses indicated that the PCI is unidimensional and it has adequate internal consistency. Correlational analyses confirmed that the PCI is associated with psychological distress and deficits in cognitive self-management, including lack of self-reinforcement, lack of a positive self-focus, and perfectionistic inflexibility. Moreover, tests of incremental validity revealed that the PCI accounts for unique variance in levels of anxiety and depression symptoms after removing variance attributable to trait perfectionism dimensions. Overall, the findings suggest that automatic thoughts involving perfectionistic themes can be assessed in a reliable and valid manner in clinical samples. Moreover, it is important to assess perfectionism cognitions as a supplement to trait perfectionism measures when evaluating the role of perfectionism in psychological distress and associated deficits in cognitive self-control. This research was supported by major research grants from Health Canada and the Social Sciences and Humanities Research Council (SSHRC) of Canada to the first two authors, and a Canada Research Chair in Personality & Health awarded to the first author. The fourth author, Thomas Martin, is now deceased and this paper is dedicated to his memory.     

Affective and cognitive religiosity: Influences on consumer reactance and self‐control

Self‐control is regularly studied in the marketing literature in relation to spending and food consumption; however, little research has assessed trait characteristics that influence consumers' self‐control. Although prior research in other fields has shown a generally positive relationship between religiosity and self‐control, such research has often used poor measures of religiosity and has inadequately examined marketplace outcomes or factors underlying consumers' self‐controlled responses. Thus, the studies herein build on self‐regulation theory to address and extend from these limitations by examining the influence of religiosity, as a multidimensional construct (particularly affective and cognitive religiosity), on self‐control and resulting influences on marketplace behaviors. Findings reveal that priming affectively (cognitively) religious consumers leads to greater (lower) consumer self‐control with a religious message prime (Study 1) and religious writing task (Study 2). Additionally, findings show that psychological reactance is at the root of these responses (Study 3). Implications build on self‐regulation theory and the strength model of self‐control to show the importance of religiosity (particularly affective and cognitive religiosity), interactions with religious primes, and psychological reactance in understanding consumers' self‐control.     

Inference making and linking both require thinking: Spontaneous trait inference and spontaneous trait transference both rely on working memory capacity

Past research suggests that spontaneous trait inference (STI) and spontaneous trait transference (STT) may reflect different cognitive processes, the former being inferential and the latter associational. The present research was designed to explore whether either or both of these processes involve thinking that occupies cognitive capacity. Four studies suggest that reductions in available cognitive capacity reduce both STI and STT effects, both on measures of savings in relearning (which reflect the strength of trait associations with a person) and on trait ratings measures (which reflect the strength of trait inferences made about a person). Similar results were obtained using an individual difference measure of cognitive capacity. Although these results suggest that STI and STT are similar, in that both exhibit interference from reductions in cognitive capacity, other results, such as halo effects in trait ratings, support previous assertions that their underlying processes are distinct.     

Hypnotic suggestibility,cognitive inhibition,and dissociation

We examined two potential correlates of hypnotic suggestibility: dissociation and cognitive inhibition. Dissociation is the foundation of two of the major theories of hypnosis and other theories commonly postulate that hypnotic responding is a result of attentional abilities (including inhibition). Participants were administered the Waterloo-Stanford Group Scale of Hypnotic Susceptibility, Form C. Under the guise of an unrelated study, 180 of these participants also completed: a version of the Dissociative Experiences Scale that is normally distributed in non-clinical populations; a latent inhibition task, a spatial negative priming task, and a memory task designed to measure negative priming. The data ruled out even moderate correlations between hypnotic suggestibility and all the measures of dissociation and cognitive inhibition overall, though they also indicated gender differences. The results are a challenge for existing theories of hypnosis.     

Effects of information type on children’s interrogative suggestibility: is Theory-of-Mind involved?

This research was aimed at learning more about the different psychological mechanisms underlying children’s suggestibility to leading questions, on the one hand, and children’s suggestibility to negative feedback, on the other, by distinguishing between interview questions concerning different types of information. Results showed that, unlike the developmental pattern of children’s suggestibility to leading questions, the developmental pattern of children’s suggestibility to negative feedback differed depending on whether the interview questions concerned external facts (physical states and events) or internal facts (mental states and events). This difference was not manifested in response to questions concerning central versus peripheral facts. Results are interpreted in terms of the hypothesis that children’s suggestibility to negative feedback is differently affected by “Theory-of-Mind” abilities than children’s suggestibility to leading questions. Further research is needed in order to test this hypothesis.     

Measuring interrogative suggestibility with the Italian version of the Gudjonsson Suggestibility Scales (GSS): Factor structure and discriminant validity

The current paper provides an examination of the factor structure and discriminant validity of the Gudjonsson Suggestibility Scale (GSS 1) and of its parallel form (GSS 2), as measures of interrogative suggestibility. In Study 1, we administered the two instruments to large Italian normative samples and we run Confirmatory Factor Analyses to evaluate the factorial structure of the subscales of GSS (Yield 1, Yield 2, and Shift). In Study 2, the GSS were administered together with cognitive, personality and affect measures. A three-factor solution was proposed to account for the factorial structure of both GSS 1 and GSS 2. This solution is consistent with the theory according to which the suggestive items of Yield 1, Yield 2 and Shift subscales correspond to separate aspects of the general construct of interrogative suggestibility. Furthermore, the results of the present research confirm that GSS 1 and GSS 2 satisfactorily discriminate interrogative suggestibility from cognitive, personality and affect constructs.

Hypnotic interviewing: the best way to interview eyewitnesses?

It has been suggested that hypnosis techniques may have the potential to enhance eyewitness memory in forensic investigations. However, laboratory research shows that increases in recall with hypnosis techniques are often associated with decreases in accuracy, false confidence in incorrect information, and increased suggestibility to leading questions and misleading post-event information. These problems limit the usefulness of hypnosis as an interviewing procedure. However, in practical investigations, many factors associated with hypnosis, apart from the hypnotic induction itself, might lead to memory enhancement compared with standard police interviews. For example, hypnotic interviewers, because of their psychological, clinical, and interpersonal skills, may be better interviewers than police officers. They may use effective interviewing strategies such as those associated with the “cognitive interview”; a procedure which has the potential to enhance recall by approximately 35% without the problems of memory distortion associated with hypnosis. It is concluded, therefore, that a cognitive interview procedure should be used in preference to hypnosis. © 1998 John Wiley & Sons, Ltd.     

正念研究的分歧：概念与测量

正念是当代临床健康心理学领域出现的一个新概念, 尽管其应用在临床领域取得了瞩目的成绩, 但对于正念的理论研究却亟待加强。在对正念的三阶段概念演进过程及四种取向的测量工具进行了系统梳理与评价后, 发现目前对正念的理论研究存在两大问题。一是概念不够清晰, 它可以指代一种行为(冥想)、心理状态、心理过程, 甚至是一种人格或类人格特质; 二是测量过于多元, 有状态取向、能力取向、认知取向和特质取向。两大问题的核心在于如何理解正念。基于对问题的分析及以往实证研究, 建议可以借鉴价值实践分类体系(Values In Action Classification), 以类特质为取向, 采用兼顾文化共同性和特殊性的方法, 深入挖掘其独特的核心内涵, 在命名、测量上突显个体对当下经验留心的基本特点。     

Imaginative Suggestibility and Hypnotizability

More than a half-century of research aimed at identifying the predictors of hypnotic responding has been described as investigations of 'hypnotizability'. Most of that research, however, has disregarded the well-established findings that (a) people respond to suggestion without being hypnotized almost as much as they do following a hypnotic induction, and (b) nonhypnotic and hypnotic suggestibility are highly correlated. More recent studies have provided the first empirical data on predictors of individual differences in response to the induction of hypnosis. These studies indicate that individual differences in hypnotic suggestibility can be accounted for completely by nonhypnotic suggestibility, expectancy, motivation, and reaction time. Because the amount of variance accounted for is as great as the reliability of the hypnotic-suggestibility scale, and because nonhypnotic suggestibility has been controlled, no additional variables are necessary to account for hypnotic suggestibility.     

Historical background to suggestibility: How interrogative suggestibility differs from other types of suggestibility

This paper reviews the literature on suggestibility and it is argued that ‘interrogative suggestibility’ bears little resemblance to traditional types of suggestibility and requires a separate model of understanding. The distinguishing features of interrogative suggestibility are: (i) it involves a questioning procedure within a closed social interaction; (ii) the questions are mainly concerned with past experiences and events; and (iii) it has a strong ‘uncertainty’ component related to cognitive functioning.     

Psychosocial Adjustment in Male-to-Female Transsexuals: An Overview of the Research Evidence

Transsexualism has been defined as an extreme gender dysphoria; it refers to unhappiness with one's biological sex and the desire to have the body of the opposite sex and to be regarded by others as a member of that other sex. Transsexualism is not a common condition, but its prevalence is not yet known. A large number of transsexuals receive hormonal treatment and sex reassignment surgery (SRS). In spite of years of poor quality research, due in part to methodological problems, recent research on surgical outcomes has provided important information. However, psychological research into transsexualism has ignored the cognitive style and psychological functioning of transsexuals, and very little effort has been made to incorporate research findings into the development of psychological treatments to improve the quality of life for transsexuals.     

Individual and developmental differences in eyewitness recall and suggestibility in children with intellectual disabilities

This study examined two key issues: (1) whether there were developmental improvements in eyewitness memory performance for children with intellectual disabilities (ID); and (2) whether standardised measures of cognitive ability and suggestibility would relate to eyewitness recall and suggestibility. Children with ID and age‐matched controls (ages 8/9 and 12 years) watched a video of a crime and were asked a range of open‐ended and specific questions about the event in a subsequent interview. Free recall increased between the two age levels for children with and without ID, but at a faster rate for those without ID. For other question types, differences in performance between children with and without ID were far more marked than age differences. Standardised measures of interrogative suggestibility (Gudjonsson Suggestibility Scale, GSS), verbal IQ, non‐verbal IQ, mental age and speed of information processing were related to eyewitness performance. In particular, higher eyewitness recall scores (free recall, non‐leading specific questions) were related to higher scores on the standardised GSS free recall measure; and higher eyewitness suggestibility scores were related to higher scores on the standardised GSS suggestibility measures. Mental age was a better predictor of performance on a range of eyewitness memory question types than verbal or non‐verbal IQ; and speed of information processing showed some relationships with eyewitness performance.

Day-to-day body-image states: prospective predictors of intra-individual level and variability

Most body-image research has focused on the trait level of body-image evaluation, often neglecting the momentary fluctuations many people experience in everyday life. The present prospective study investigated whether theory-relevant body-image measures, perfectionistic self-presentation, and eating attitudes would predict average day-to-day body-image levels and their intra-individual variability. A convenience sample consisted of 121 women from two universities. In Phase 1 of the study, participants completed an online battery of selected body-image and personality questionnaires. In Phase 2, participants went online to complete the dependent measure, the Body Image States Scale, once per evening over 10 days. As hypothesized, more favorable body-image state levels were associated with less investment in appearance for self-worth, less body-image disturbance, fewer body-image cognitive distortions, less disturbed eating attitudes, and lower body mass. Moreover, greater day-to-day body-image variability was predicted by greater psychological investment in appearance, more body-image cognitive distortions, and higher perfectionistic self-presentation. Implications and future directions for research are discussed.
