The Use of Structured Imagery and Dispositional Measurement to Assess Situational Use of Mindfulness Skills

The recent proliferation of studies on mindfulness produced varying theoretical models, each based in part on how mindfulness is assessed. These models agree, however, that mindfulness encompasses moment-to-moment or situational experiences. Incongruence between dispositional and situational assessment would be problematic for theory and empirical research. In particular, it remains to be established whether situational measurement is an accurate method for mindfulness assessment and whether dispositional measures are able to accurately detect mindfulness skills in various situations. The association between dispositional and situational mindfulness processes (i.e., situational attention awareness and emotion acceptance) was examined in two studies. In Study 1 (N = 148), independent groups who reported high and low levels of dispositional mindfulness skills were compared on a continuous measure of situational mindfulness skills. In Study 2 (N = 317), dispositional mindfulness questionnaires were used to predict situational use of mindfulness skills. Results suggest not only that situational measures accurately detect use of mindfulness skills, but also that dispositional measures can predict one\u27s use of situational mindfulness skills. Findings from both studies were consistent across both positive and negative situations. Moreover, neither neuroticism nor extraversion was shown to have a moderating effect on the relationship between dispositional and situational use of mindfulness skills. The implications of these findings for clinical practice and future investigations pertaining to measurement validity in this area are discussed

Ambulatory Electromyogram Activity in the Upper Trapezius Region: Patients With Muscle Pain vs. Pain-free Control Subjects

Study Design: This study compared the ambulatory electromyogram activity of persons reporting pain in the shoulder and cervical regions with an equal group of persons not reporting such pain. Ambulatory electromyogram data were obtained over 3-day periods. In addition, all participants completed several standard psychological questionnaires. Objectives: The results were analyzed with inferential statistics to determine whether subjects reporting significant pain in the shoulder and cervical regions had greater ambulatory electromyogram activity than an equal number of subjects not reporting pain. Summary of Background Data: Considerable controversy exists regarding the role of muscle activity in the etiology and maintenance of muscle pain disorders. Given the availability of ambulatory recording devices that can provide a detailed record of muscle activity over an extended period of time, the present research was conducted to determine whether persons reporting shoulder and cervical pain could be differentiated from a group of normal subjects. Methods: All subjects (N = 20) completed a battery of tests with standardized psychometric instruments and then were fitted with ambulatory electromyogram monitors to record electromyographic activity of the upper trapezius region of the dominant side; the time, duration, and amplitude of electromyogram activity greater than 2 μV was recorded. The monitors were worn during normal working hours (mean, 6.2 hours per day) over 3 consecutive days. In addition to wearing the monitors, all subjects completed hourly self-ratings of perceived muscle tension during the recording periods. Results: As expected, subjects with muscle pain reported significantly more pain (mean, 4.9) than did the normal control subjects (mean, 0.9), t(15) = 3.29, P \u3c 0.01. However, patients with muscle pain did not have greater average electromyogram activity (mean, 6.4 μV) over the 3-day period as compared to the normal controls (mean, 7.1 μV), t(18) = -0.25, P \u3c 0.80. Self-monitoring of perceived muscle tension also did not reveal differences between pain subjects and the normal control subjects (P \u3c 0.75). Conclusions: Ambulatory measurements of electromyogram activity did not differentiate persons reporting upper trapezius or cervical pain from those that did not report such pain. Persons reporting pain are also not distinguishable from normal control subjects on a variety of self-report measures. These results raise questions regarding the role of ambulatory electromyogram recordings in the evaluation and treatment of muscle pain disorders

Impact of Amputation of the Upper Limb and Prostheses on Perceptions of Competence, Warmth, and Functional Abilities: Dataset

Purpose/Objective: This study investigated attitudes that young adults have towards individuals with amputation of the upper limb (AUL). Previous studies have found that people tend to feel sympathy towards these individuals, but they are also perceived as less competent in various situations. However, it is unclear if these perceptions are influenced by factors such as the cause of amputation, the gender of the amputee, whether they use a prosthesis or not, or the type of prosthesis. Research Method/Design: The survey included 469 participants from a university in the southeastern United States. Participants rated pictures of individuals with or without amputation, and with and without prostheses after reading a brief background scenario. Images were rated using a semantic differential for competence and warmth, and a scale of functional ability. Results: Factorial ANOVAs produced significant main effects indicating individuals with AULs who used prostheses were rated with higher competence and ability than individuals with AULs who did not use prostheses. Females were rated with lower competence and ability, and higher warmth regardless of AULs status. Higher ability ratings were obtained for individuals with advanced technology prostheses as compared to bodypowered prostheses. Conclusions/Implications: Findings indicate that attitudes towards individuals with AUL are generally positive when they use prostheses, but traditional stereotypes persist for those who do not. Negative sex biases were more extreme with AUL. Cause of amputation did not influence ratings. Prostheses that appear to be of advanced technology positively influenced ratings of functional ability when compared to traditional body powered types

Affective And Autonomic Responses To Erotic Images: Evidence Of Disgust-Based Mechanisms In Female Sexual Interest/Arousal Disorder

Disgust has recently been implicated in the development and maintenance of female sexual dysfunction, yet most empirical studies have been conducted with a sexually healthy sample. The current study contributes to the literature by expanding the application of a disgust model of sexual functioning to a clinically relevant sample of women with low sexual desire/arousal and accompanying sexual distress. Young women (mean age = 19.12 years) with psychometrically defined sexual dysfunction (i.e., female sexual interest/arousal disorder [FSIAD] group) and a healthy control group were compared in their affective (i.e., facial electromyography [EMG] and self-report) and autonomic (i.e., heart rate and electrodermal activity) responses to disgusting, erotic, positive, and neutral images. Significant differences were predicted in responses to erotic images only. Specifically, it was hypothesized that the FSIAD group would display affective and autonomic responses consistent with a disgust response, while responses from the control group would align with a general appetitive response. Results largely supported study hypotheses. The FSIAD group displayed significantly greater negative facial affect, reported more subjective disgust, and recorded greater heart rate deceleration than the control group in response to erotic stimuli. Greater subjective disgust response corresponded with more sexual avoidance behavior. Planned follow-up analyses explored correlates of subjective disgust responses

Comorbidity of schizotypy and psychopathy: Skin conductance to affective pictures

Prior research indicates a relationship between psychopathy and schizophrenia, elucidating a specific trajectory toward violence. Recent research has suggested that this relationship exists at the nonclinical trait level of schizotypy; however, this finding has not been examined objectively. To explore this relationship using both subjective and objective measures, 54 undergraduates (50% male; mean age 20.41) who endorsed a wide range of schizotypy on the Schizotypal Personality Questionnaire (SPQ) completed a laboratory-based protocol. Participants viewed 15 pictures (five neutral, five threatening, and five of others in distress) from the International Affective Pictures System while electrodermal activity was recorded. As expected, all participants exhibited increased skin conductance levels (SCL) to threat and distress pictures compared to neutral pictures; however, no difference in SCL was found between threat and distress pictures. A unique relationship between psychopathy and schizotypy was found (i.e., schizotypy was related to higher Self-Centered Impulsivity and lower Fearless Dominance); however, schizotypy was related to increased SCL in response to emotional and neutral pictures. Although results do not support autonomic hyporesponsiveness often found in clinical psychopathy, a positive relationship was found between schizotypy and self-reported physical aggression. Findings highlight the need to examine other trajectories of violence within the schizophrenia spectrum disorders. © 2013 Elsevier Ireland Ltd

Gastrointestinal functioning and menstrual cycle phase in emerging young adult women: a cross-sectional study

Abstract Background Women experience more severe gastrointestinal (GI) symptoms compared to men. The onset of puberty and the menstrual cycle may influence these differences. Additionally, health anxiety is an important construct that has been shown to play a role in increased symptomatology across many medical conditions. Using standardized clinical measures often employed to assess disorders of gut-brain interaction (DGBI) we aimed to identify differences of GI functioning across menstrual cycle phases and to evaluate the role of health anxiety in this relationship. Methods Six hundred three participants completed a survey including functional GI assessment scales (PROMIS-GI®), an abdominal pain scale and map, and a health anxiety measure. They were grouped by menstrual cycle phases (Menses, Follicular, Early-Luteal, and Premenstrual) based on self-reported start date of most recent period. Multivariate analyses of covariance were conducted to identify differences between menstrual cycle phase and scores on the symptom scales. Heath anxiety was included as a covariate in all analyses. Results No significant differences were found between menstrual cycle group and PROMIS-GI scores. Higher GI-symptom and pain levels were found as health anxiety increased. Pain in the hypogastric region of the abdomen was significantly higher during the Menses phase when compared to Early-Luteal and Premenstrual phases. A subset of participants with DGBI diagnoses demonstrated significantly higher GI-symptom severity on several PROMIS-GI scales when compared to matched controls who did not have those diagnoses. In addition, participants with DGBI diagnoses reported significantly greater pain across multiple abdominal regions than their non-diagnosed counterparts. Conclusions GI symptom levels as measured by the PROMIS-GI scales in otherwise healthy women were not dependent on menstrual cycle phase. Yet, the PROMIS-GI scales were sensitive to symptom differences in women with DGBI diagnoses. Overall, this study demonstrated that the PROMIS-GI measures are unlikely to be affected by gynecological functioning in healthy young women. We argue that the abdominal pain map is an essential addition to classification and diagnosis

Natural Contact And Stigma Towards Schizophrenia In African Americans: Is Perceived Dangerousness A Threat Or Challenge Response?

This research extends our understanding of the relationship of social contact theory to stigma in a sample of mainly African American college students. In Phase 1, 75 participants with high levels of contact reported significantly lower negative affect and less social distance toward the mentally ill as compared to 89 participants with low contact. Despite this, the high contact group attributed significantly higher levels of dangerousness to the mentally ill. Thus while social contact was associated with reductions in some dimensions of stigma, it was associated with higher levels of self-reported perceived dangerousness. These results were obtained while controlling for social desirability bias in the self-report measures of stigma. The results from Phase 1 of this study may indicate fundamental differences between incidental social contact and that which occurs in an assistive context. In Phase 2, a subset of convenience from the high contact group (n = 27) and the low contact group (n = 38) were compared on cardiovascular reactivity measures while imagining social interactions with people labeled with schizophrenia. Post hoc testing revealed that when participants from the high contact group imagined interacting with people labeled as schizophrenic they exhibited significant decreases in total peripheral resistance (TPR), the challenge pattern, compared to their reactions when they imagined interacting with unstigmatized people. This finding suggests the higher dangerousness ratings of the mentally ill sometimes found in African American samples may be related to factors other than direct threat. © 2011 Elsevier B.V
