The interpretation of change in verbal reports: Implications for health psychology

Abstract

This paper raises a number of issues for health psychology in relation to the interpretation of change in verbal reports. Drawing on a typology of change developed to evaluate organisational interventions, it is suggested that change may occur at an alpha level (e.g. changed health status), beta level (e.g. a recalibration of the respondent's scale for assessing health status) or gamma level (e.g. a reconceptualisation of the meaning attached to health). Given the likely presence of beta and/or gamma change in intervention data in health psychology, researchers may be analysing their change data at an inappropriate level. A number of existing methodologies which attempt to detect beta and gamma change are presented and discussed. The need to develop further methodologies which focus more explicitly on the nature of change is highlighted. Finally, the proposed typology has a number of practical implications for the design of health promotion interventions.     

Name ambiguity and androgyny

Subjects with gender-ambiguous names or nicknames (i.e., names that can belong to either males or females) were compared on Bem's androgyny scale to subjects having common or uncommon first names or nicknames to determine if name ambiguity was related to sex-role identification. The results showed that for our sample of college undergraduates (N=489), both males (N=246) and females (N=243) with ambiguous nicknames (e.g., Pat, Tony, Marty) were more often classified as androgynous on the Bem inventory than were subjects with uncommon, common, or no nicknames. Ambiguous first names were unrelated to the androgyny scale. Name and nickname ambiguity were not related to liking of name, self-concept, family tradition, social class differences, or grade point average.A version of this paper was presented at the annual meeting of the Southeastern Psychological Association, Atlanta, March 1978.     

Investigating Psychometric Properties of Social Media Addiction Measures Among Adolescents

Assessment has a long history in counseling, with scholars noting multiple benefits to using assessment instruments in determining client strengths and needs as well as establishing relevant treatment goals. However, when counselors use unreliable or invalid instruments, they gather results that are ill equipped to inform clinical decision-making. Consequently, we evaluated and compared the psychometric properties of three scales of social media addiction—the Social Media Disorder Scale (van den Eijnden et al., 2016), the Bergen Social Media Addiction Scale (Andreassen et al., 2012, 2016), and the Social Media Addiction Scale (Al-Menayes, 2015)—to inform clinical use. Adolescents (N = 440) between the ages of 13 and 19 completed the scales. Results indicated that each scale provides a reliable and valid measurement of problematic social media use or addiction among adolescents. We provide recommendations for choosing a social media assessment and for future research.     

Brain oscillations during semantic evaluation of speech

Changes in oscillatory brain activity have been related to perceptual and cognitive processes such as selective attention and memory matching. Here we examined brain oscillations, measured with electroencephalography (EEG), during a semantic speech processing task that required both lexically mediated memory matching and selective attention. Participants listened to nouns spoken in male and female voices, and detected an animate target (p = 20%) in a train of inanimate standards or vice versa. For a control task, subjects listened to the same words and detected a target male voice in standards of a female voice or vice versa. The standard trials of the semantic task showed enhanced upper beta (25–30 Hz) and gamma band (GBA, 30–60 Hz) activity compared to the voice task. Upper beta and GBA enhancement was accompanied by a suppression of alpha (8–12 Hz) and lower to mid beta (13–20 Hz) activity mainly localized to posterior electrodes. Enhancement of phase-locked theta activity peaking near 275 ms also occurred over the midline electrodes. Theta, upper beta, and gamma band enhancement may reflect lexically mediated template matching in auditory memory, whereas the alpha and beta suppression likely indicate increased attentional processes and memory demands.     

Clarifying the Relation Between Extraversion and Positive Affect

This article clarifies two sources of ambiguity surrounding the relation between extraversion and positive affect. First, positive affect is defined differently across major models of the structure of affect. Second, no previous research has examined potentially diverging associations of lower‐order aspects of extraversion (i.e., assertiveness and enthusiasm) with positive affect. Australian (Study 1: N = 437, 78% female, M_age = 20.41) and American (Study 2: N = 262, 39% female, M_age = 33.86) participants completed multiple measures of extraversion and positive affect. Correlations were employed to examine relations among these measures. In both studies, extraversion was most clearly associated with positive affect as conceptualized within a major factor model of affect—specifically, as positive activation (Watson & Tellegen, 1985)—rather than the valence‐based conceptualization of positive affect provided by a circumplex model of affect (Russell, 1980). This was also the case for the assertiveness and enthusiasm aspects of extraversion. Our findings clarify the nature of the positive affective component of extraversion, which is best described in terms of both positive valence and high activation.     

Comprehensive Intervention for Anxiety and Depression among the Community Elderly with Tuberculosis

Anxiety and depression are common comorbidities in the elderly who have tuberculosis. We conducted a community-based trial to explore the effect of comprehensive interventions on anxiety and depression of the elderly tuberculosis patients. The control group (n?=?122) received health education, and the intervention group (n?=?61) received health education, psychotherapy, home visit, peer support, and psycho-educational workshops. Compared with the control group, the anxiety (β_Group×Time = ?0.79) and depression (β_Group×Time = ?1.13) declined more pronounced in the intervention group. The results suggested that comprehensive interventions could alleviate the anxiety and depression of the elderly tuberculosis patients sustainably and effectively.     

Examination of the reliability and validity of the personality assessment inventory

The reliability, discriminant validity, and construct validity of the Personality Assessment Inventory (PAI) — a multidimensional self-report measure of abnormal personality traits — were examined within the Australian context. Subjects included 151 normals, 30 alcoholics, and 30 schizophrenic patients. A subsample of 70 nonpsychiatric adults responded to the PAI items twice over a test-retest interval of 28 days. The resulting median retest coefficient was 0.7, indicating less than optimal stability. The median alpha (KR₂₁) coefficient was 0.8, suggesting somewhat narrow measurement scales. A significant multivariate main effect was obtained across groups after the effects of age and gender were removed. Multiple comparisons for each of the PAI scales revealed significant differences between the respective groups, as discussed. A higher-order scale factoring did not strongly support the purported PAI structure. In reanalyses of the correlation matrices included in the Professional Manual, the purported PAI factor structure was unable to be replicated for the standardization clinical sample (N=1246), and a confirmatory factor analysis using the normative (validation) correlational data (N=1000) revealed poor fit indices, raising further concerns about construct validity.     

The Wax and Wane of Narcissism: Grandiose Narcissism as a Process or State

Though grandiose narcissism has predominantly been studied in structural terms—focused on individuals' general tendencies to be more or less narcissistic—we tested whether it also has a meaningful process or state component. Using a daily diary study methodology and multilevel modeling (N = 178 undergraduates, 146 female; M_age = 18.86, SD = 2.21), we examine whether there is significant variability in daily state narcissism and whether this variability relates systematically to other psychological states (i.e., self‐esteem, stress) and daily events. We assessed state narcissism and daily experiences over a 10‐day period. We observed significant within‐person variability in daily narcissism. Notably, this variability was not simply random error, as it related systematically to other psychological states and daily events. Specifically, state narcissism was higher when people experienced more positive agentic outcomes (e.g., having power over someone) or more positive communal outcomes (e.g., helping someone with a problem). State narcissism was lower on days people experienced greater felt stress. These relations held when state self‐esteem, gender, and trait narcissism were controlled. These findings suggest that grandiose narcissism has a meaningful process or state component.     

The Turkish Version of the Meaning in Life Questionnaire: Assessing the Measurement Invariance Across Turkish and American Adult Samples

The purpose of this study was to adapt the Meaning in Life Questionnaire (MLQ) developed by Steger, Frazier, Oishi, and Kaler (2006) into Turkish and examine the measurement and structural invariance of this scale across Turkish (N = 815) and U.S. (N = 207) samples. Our findings indicated that the hypothesized 2-factor model of the MLQ fit the data well for both Turkish and U.S. samples. Results also provided support for the full metric invariance, partial scalar invariance, and partial invariance of residual variances of the MLQ across the 2 samples (i.e., Turkish and U.S.). Supporting the structural invariance, we found that factor variances and covariances were equivalent across the 2 groups. Internal consistency reliability analyses revealed a Cronbach's alpha value of .88 for the MLQ Presence scale and .90 for the Search scale. Our findings also provided preliminary support for the convergent validity of the Turkish version of the MLQ (MLQ–TR). Contrary to findings in other collectivist cultures, the relationship between Search and Presence was negative in Turkish culture. These results support the psychometric properties of the MLQ–TR and its partial equivalence to the original U.S. version.     

Religious Perfectionism Scale Among Believers of Multiple Faiths in China: Development and Psychometric Analysis

In China, many people are converting to various world religions. Nonetheless, religious adherence for them, as with many people, can still function as a double-edged sword with regards to mental health. In particular, religious perfection can become either a healthy commitment or a rigid outlook that leads to distress. Thus, we developed the Religious Perfectionism Scale (RPS) from Chinese religious believers. In the first phase (N = 171), we collected qualitative data through an open-question survey from different religious groups (i.e., Buddhism, Protestantism, and Islam). Then, we developed an item pool based on themes that emerged from these qualitative data. In the second phase, participants (N = 1055) were randomly split into two subsamples. Exploratory factor analyses were performed on the first subsample (N = 519) to select the scale items. The nine-item RPS subsequently includes two dimensions—Zealous Religious Dedication and Religious Self-Criticism. Confirmatory factor analyses (CFA) were performed on the second subsample (N = 536) to cross-validate the factor structure. Results indicate that the internal consistency reliability for the RPS subscale scores was all adequate. Furthermore, the construct validity of the RPS was supported through its correlations with measures of perfectionism perceived to have come from God (or a higher power), psychological indicators, and a personality variable (i.e., discipline) in expected directions. Results of the psychometric evaluations of this newly developed scale suggest that the RPS is a promising measure in that it can facilitate future research that leads to a more comprehensive understanding of the impact of religious perfectionism on psychological well-being.

     

Modification of the optical band gap of polyethylene by irradiation with electrons and gamma rays

Irradiation of polymers has become an important technique in producing special materials for electronic applications. In this study, the effects of electron and gamma irradiation on ultra-high-molecular-weight polyethylene (UHMWPE) samples have been studied using UV–Vis absorption spectroscopy. The UHMWPE samples were irradiated with electron and gamma rays with doses ranging from 25 kGy up to 500 kGy. An increase in the optical absorption and a shifting from the UV–Vis towards longer wavelengths were observed. Concomitantly, a pronounced decrease in the optical band gap was recorded as a function of dose level. The optical band gap E _g varied from 2.86 eV for a pristine sample down to ～1.98 eV and ～2 eV for samples irradiated with gamma rays and electrons at the highest doses, respectively. A correlation between E _g and the number of carbon atoms N in a formed cluster is discussed in terms of a modified Tauc equation.     

Mapping differential responses to cognitive training using machine learning

We used two simple unsupervised machine learning techniques to identify differential trajectories of change in children who undergo intensive working memory (WM) training. We used self‐organizing maps (SOMs)—a type of simple artificial neural network—to represent multivariate cognitive training data, and then tested whether the way tasks are represented changed as a result of training. The patterns of change we observed in the SOM weight matrices implied that the processes drawn upon to perform WM tasks changed following training. This was then combined with K‐means clustering to identify distinct groups of children who respond to the training in different ways. Firstly, the K‐means clustering was applied to an independent large sample (N = 616, M_age = 9.16 years, range = 5.16–17.91 years) to identify subgroups. We then allocated children who had been through cognitive training (N = 179, M_age = 9.00 years, range = 7.08–11.50 years) to these same four subgroups, both before and after their training. In doing so, we were able to map their improvement trajectories. Scores on a separate measure of fluid intelligence were predictive of a child's improvement trajectory. This paper provides an alternative approach to analysing cognitive training data that go beyond considering changes in individual tasks. This proof‐of‐principle demonstrates a potentially powerful way of distinguishing task‐specific from domain‐general changes following training and of establishing different profiles of response to training.     

Feeling Hopeful Inspires Support for Social Change

Hope is an emotion that has been implicated in social change efforts, yet little research has examined whether feeling hopeful actually motivates support for social change. Study 1 (N = 274) confirmed that hope is associated with greater support for social change in two countries with different political contexts. Study 2 (N = 165) revealed that hope predicts support for social change over and above other emotions often investigated in collective action research. Study 3 (N = 100) replicated this finding using a hope scale and showed the effect occurs independent of positive mood. Study 4 (N = 58) demonstrated experimentally that hope motivates support for social change. In all four studies, the effect of hope was mediated by perceived efficacy to achieve social equality. This research confirms the motivating potential of hope and illustrates the power of this emotion in generating social change.     

Simultaneous classical conditioning of two effector systems

The experiment reported here was an attempt to develop an experimental procedure for independent classical conditioning of two different response systems, the skin conductance response (SCR) and the eyelid response. In a differential conditioning design with human subjects (N=50) two different unconditioned stimuli were used, a white noise (US₁) and an airpuff (US₂). Two conditioned stimuli (CS₁₁ and CS₁₂) were paired with US₁, and two other CSs (CS₂₁ and CS₂₂) were paired with US₂. A special trial architecture was used to accomplish measurement of both anticipatory SCR and eyelid responses during each trial. Significant eyelid differentiation as well as significant SCR (especially second interval responses) differentiation developed.     

The Cognitive Demands of Gait Retraining in Runners: An EEG Study

Abstract

High impact forces during running have been associated with tibial stress injuries. Previous research has demonstrated increasing step rate will decrease impact forces during running. However, no research has determined the cognitive demand of gait retraining. The primary purpose was to determine the cognitive demand and effectiveness of field-based gait retraining. We hypothesized that in-field gait retraining would alter running mechanics without increasing cognitive workload as measured by EEG following learning. Runners with a history of tibial injury completed a gait retraining protocol which included a baseline run, retraining phase, practice phase, and re-assessment following retraining protocol. Results demonstrated an increase in the theta, beta, and gamma power within prefrontal cortex during new learning and corresponding return to baseline following skill acquisition and changes across alpha, beta, gamma, mu, and theta in the motor cortex (p < .05). In the midline superior parietal cortex, spectral power was greater for theta activity during new learning with a corresponding alpha suppression. Overall, the results demonstrated the use of EEG as an effective tool to measure cognitive demand for implicit motor learning and the effectiveness of in-field gait retraining.     

Establishing Measurement Equivalence and Invariance in Longitudinal Data With Item Response Theory

If measurement invariance does not hold over 2 or more measurement occasions, differences in observed scores are not directly interpretable. Golembiewski, Billingsley, and Yeager (1976) identified 2 types of psychometric differences over time as beta change and gamma change. Gamma change is a fundamental change in thinking about the nature of a construct over time. Beta change can be described as respondents' change in calibration of the response scale over time. Recently, researchers have had considerable success establishing measurement invariance using confirmatory factor analytic (CFA) techniques. However, the use of item response theory (IRT) techniques for assessing item parameter drift can provide additional useful information regarding the psychometric equivalence of a measure over time that is not attainable with traditional CFA techniques. This article marries the terminology commonly used in CFA and IRT techniques and illustrates real advantages for identifying beta change over time with IRT methods rather than typical CFA methods, utilizing a longitudinal assessment of job satisfaction as an example.     

Score blending: How scale response grouping biases perceived standing

Numerical values—from test scores to credit scores—inform us of our relative standing and can shape our decisions. The values are usually presented in a continuous format (which places scores on a single line) or a grouped format (which separates scores into several score groups). We investigate whether and how the presentation format affects one's perception of their standing in a distribution and subsequent decision making. We show that when values are grouped, individuals merge the values within each group, a phenomenon we term score blending, which leads to an underweighting of intragroup score shifts and an overweighting of intergroup score shifts. Across six studies (N = 2,108) and a variety of paradigms (e.g., test taking and financial decision making), we observe robust effects of score blending, even when score groups are explicitly described as meaningless and generated randomly. The effect persists when the score is merely recalled without the scale present and can bias key decision parameters with behavioral consequences.     

Investigating the role of E-contact and self-disclosure on improving Turkish-Kurdish interethnic relations

While recent research has started to pay more attention to the role of contact strategies on promoting intergroup harmony between Turkish and Kurdish communities, the effectiveness of a novel form of indirect contact strategy, E-contact—where participants engage in a cooperative and structured online interaction with an individual from the outgroup—has not yet been tested. Across two studies (N_{Study 1} = 110, N_{Study 2} = 176), we investigated the effects of E-contact among Turks on promoting positive attitudes and behavioral tendencies toward Kurds, testing outgroup trust and intergroup anxiety as mediators and incorporating a distinction between lower and higher self-disclosure conditions. As expected, E-contact led to more positive outgroup attitudes, as well as greater approach tendencies and decreased avoidance tendencies through increased outgroup trust (Studies 1 and 2) and reduced intergroup anxiety (Study 2). Study 2 also found that E-contact produced lower perceived interethnic conflict through increased outgroup trust. While both lower and higher personal disclosure conditions provided similar effects in the two studies, E-contact with heightened self-disclosure was especially effective at promoting more positive outgroup attitudes and reducing avoidance tendencies. Findings highlight potential benefits of using E-contact as a prejudice-reduction strategy in conflict settings.     

How Do Employees Construe Their Career Success: An improved measure of subjective career success

Subjective career success has long been of interest to scholars because of its importance in the career area. However, the subjective career success literature suffers from the lack of measurement. To fill this void, after reviewing the limitations of the existing instruments, the current study developed a three‐dimensional scale of subjective career success based on the framework of Zhou et al. Three independent studies were conducted using three separate samples (N = 244; N = 411; N = 254) in China to examine the reliability and validity of the developmental scale. The results provided evidence of internal homogeneity, structural validity, convergent validity, discriminant validity, and incremental validity of the developed scale. To conclude the study, the limitations of the article and implications for future study were discussed.     

Heidegger the Metaphysician: Modes‐of‐Being and Grundbegriffe

Modes‐of‐being (Seinsarten) figure centrally in Heidegger's masterwork Being and Time. Testimony to this is Heidegger's characterisation of two of his most celebrated enquiries—the Existential analytic and the Zeug analysis—as investigations into the respective modes‐of‐being of the entities concerned. Yet despite the importance of this concept, commentators disagree widely about what a mode‐of‐being is. In this paper, I systematically outline and defend a novel and exegetically grounded interpretation of this concept. Strongly opposed to Kantian readings, such as those advocated by Taylor Carman and Cristina Lafont, I interpret a mode‐of‐being as a universal that defines a district (Bezirk)—that is, a natural class of entities that ought to be conceptualised in a special way. As such, every mode‐of‐being plays an important metaphysical and epistemic role: serving both to unify a natural class of a high degree of generality and as the interpretandum of an act yielding the basic‐concepts (Grundbegriffe) pertaining to the entities therein. In explicating and arguing for this interpretation, I attribute a characteristically Aristotelian philosophical position to the early Heidegger, encompassing both metaphysical and epistemological realism and a conceptualist theory of universals.
