abstract = {Although pain is a commonly experienced and observed affective state, it is frequently misinterpreted, which leads to inadequate caregiving. Studies show the ability at estimating pain in others (estimation bias) and detecting its subtle variations (sensitivity) could emerge from independent mechanisms. While estimation bias is modulated by variables such as empathy level, pain catastrophizing tendency, and overexposure to pain, sensitivity remains unimpacted. The present study verifies if these 2 types of inaccuracies are partly explained by perceptual factors. Using reverse correlation, we measured their association with participants' mental representation of pain, or more simply put, with their expectations of what the face of a person in pain should look like. Experiment 1 shows that both parameters are associated with variations in expectations of this expression. More specifically, the estimation bias is linked with expectations characterized by salient changes in the middle face region, whereas sensitivity is associated with salient changes in the eyebrow region. Experiment 2 reveals that bias and sensitivity yield differences in emotional representations. Expectations of individuals with a lower underestimation tendency are qualitatively rated as expressing more pain and sadness, and those of individuals with a higher level of sensitivity as expressing more pain, anger, and disgust. Together, these results provide evidence for a perceptual contribution in pain inferencing that is independent of other psychosocial variables and its link to observers’ expectations. Perspective: This article reinforces the contribution of perceptual mechanisms in pain assessment. Moreover, strategies aimed to improve the reliability of individuals’ expectations regarding the appearance of facial expressions of pain could potentially be developed, and contribute to decrease inaccuracies found in pain assessment and the confusion between pain and other affective states. © 2023 United States Association for the Study of Pain, Inc.},

abstract = {Little effort has been made to systematically test the psychometric properties of the Gambling Craving Scale (GACS; Young & Wohl, 2009). The GACS is adapted from the Questionnaire on Smoking Urges (Tiffany & Drobes, 1991) and thus measures gambling-related urge. Crucially, the validation of scales assessing gambling urge is complex because this construct is better conceptualized as a state (a transient and contextdetermined phenomenon). In the present study, we tested the psychometric properties of the French version of the GACS with 2 independent samples of community gamblers following an induction procedure delivered through an audio-guided imagery sequence aimed at promoting gambling urge. This procedure was specifically used to ensure the assessment of gambling urge as a state variable. Participants also completed measures of gambling severity, gambling cognitions and motives, impulsivity, and affect. Confirmatory factor analysis showed that the original 3-factor solution (anticipation, desire, relief) did not fit the data well. Additional exploratory factor analysis suggested instead a 2-factor solution: An intention and desire to gamble dimension and a relief dimension. The factorial structure resulting from the exploratory factor analysis was tested with confirmatory factor analysis in a second independent sample, resulting in an acceptable fit. The 2 dimensions presented good internal reliability and correlated differentially with the other study's variables. The current study showed that, similar to what has been reported for substance-related urges, gambling urges are adequately probed with a bidimensional model. The findings suggest that the French GACS has good psychometric properties, legitimizing its use in research and clinical practice. © 2019 American Psychological Association.},

abstract = {Telemental health is the use of information and communications technologies and broadband networks to deliver mental health services and support wellness. Although numerous studies have demonstrated the efficiency and utility of telemental health, certain barriers may impede its implementation, including the attitudes of mental health service providers. The current study draws on the technology acceptance model (TAM) to understand the role of mental health service providers’ attitudes and perceptions of telemental health (psychotherapy delivered via videoconferencing) on their intention to use this technology with their patients. A sample of 205 broadly defined mental health service providers working on 32 First Nations reserves in the province of Quebec completed the questionnaire adapted to assess TAM for telepsychotherapy. Confirmatory factor analysis and structural equation modeling provided evidence for the factor validity and reliability of the TAM in this sample. The key predictor of the intention to use telepsychotherapy was not mental health providers’ attitude toward telepsychotherapy, nor how much they expected this service to be complicated to use, but essentially how useful they expect it to be for their First Nations patients. If telemental health via videoconferencing is to be implemented in First Nations communities, it is essential to thoroughly demonstrate its utility to mental health providers. Perceived usefulness will have a positive impact on attitudes toward this technology, and perceived ease of use will positively influence perceived usefulness. Cultural issues specific to the populations receiving telemental health services may be more efficiently addressed from the angle of perceived usefulness. © 2013, SAGE Publications.

The following information is reported for each instrument: brief description of the instrument and its development, mean and standard deviation for clinical and nonclinical samples, and psychometric properties. Four types of instruments are presented: general assessment and information (n = 2), severity of panic disorder (n = 2), body sensations (n = 2) and cognitive dimensions of panic (n = 8). Overall, it would seem that panic measures have moderate to excellent psychometric qualities. However, the comparison between the instruments is difficult because the amount of empirical support available varies widely from one instrument to the other.},

Three elements are considered before investigating its effectiveness: (a) if subjects are reliably diagnosed with schizophrenia with chronic course and severe impairment; (b) if psychotic symptoms are adequately measured; and (c) if designs are methodologically sound. Our investigation revealed that schizophrenia is not reliably diagnosed and severity is low to moderate. Assessment of psychotic symptoms is satisfactory, but assessment of generalization to other areas is limited. Only five studies possess reliable design and are performed with schizophrenia subjects. These studies suggest that cognitive restructuring is effective to reduce or eliminate hallucinations or delusions in schizophrenia patients.},

abstract = {Objective: This study aimed to answer the following questions: 1) Can we reliably measure the psychopathologic dimensions of schizophrenia by using a lifetime frame and by rating acute and interepisode periods separately? 2) Can we reproduce in subjects with familial schizophrenia the characteristic three-factor structure of schizophrenic symptoms that has been found previously ill general groups of schizophrenic patients? 3) Is the factor structure also present in familial bipolar disorder? Method: Lifetime measures of psychotic symptoms were taken through a slightly modified version of the Comprehensive Assessment of Symptoms and History for 138 patients with highly familial DSM-III-R schizophrenia (N=51), bipolar disorder (N=44), or spectrum disorders (N=43). Symptoms were rated separately in the acute episodes and in the stabilized interepisode intervals across the patients' lives. Results: A satisfactory level of reliability was obtained. In this highly familial study group, the positive/negative factorial distinction was replicated, as was a three-factor model similar to that observed in prior general groups of schizophrenic patients. These factors were also present in bipolar affective disorder. The negative, psychoticism, and disorganized factor model applied more to the acute phase of illness than to the stabilized state. Conclusions: These findings offer an empirical basis for testing biological or genetic variables in relation to negative/positive symptom dimensions, rather than diagnoses. Observations of a shared structure for schizophrenia and bipolar disorder suggest some continuity in the causes of these disorders.},
