A randomized clinical study was conducted to evaluate the effects on anxiety, depression, stress and optimism levels of an audio-recorded clinical hypnosis intervention and a music session and compare them with a control group in women scheduled for breast biopsy. We analyzed the data of 170 patients with an average age of 47 years, who were randomly assigned to each of the groups. The psychosocial variables were measured in three moments: baseline, which corresponds to the period before the intervention with hypnosis, music or waiting in the room before biopsy; a second measurement after the interventions and a third measurement after the breast biopsy procedure was finished. The results showed a statistically significant reduction in the stress (p < .001, η²p = .06); pain, (p < .01, η²p = .04); anxiety, (p < .001, ƞ²p = .07) and depression, (p < .001, ƞ²p = .05) in hypnosis and music groups compared with the control group. Before biopsy, hypnosis decrease significantly pain and depression levels compared with music, but after biopsy there were no differences between both groups. It is recommended to use audio-recorded hypnosis and music interventions to reduce physical and emotional discomfort during the biopsy procedure and to improve the quality of life of patients with suspected breast cancer.

Objective: Mindfulness or the full attention state is a factor that contributes to the successful process of aging. This study aims to evaluate the evidence of validity, on the basis of the internal structure, convergent and discriminant validity, reliability and factorial invariance across gender, for the five items Mindful Attention Awareness Scale (MAAS-5) within a sample of older adults. Methods: The participants were 323 Peruvian older adults, consisting of 160 women and 163 men, whose average ages were 68.58 (S.D = 7.23) and 68.91 years (S.D = 7.12), respectively. In addition to the MAAS-5, the Satisfaction with Life Scale and the Patient Health Questionnaire-2 were administered. Results: The Confirmatory Factor Analysis indicates that the one-factor structure of the MAAS-5 presents adequate fit for the total sample (χ² = 11.24, df = 5, χ²/df = 2.25, CFI = .99, RMSEA = .06 [90%CI: .01, .11]; and SRMR = .025), as well as for the sub-samples of men and women. This one-factor solution presents adequate internal consistency (ω = 80 [95%CI: .76 - .82]) and it is invariant across gender. Regarding convergent validity, high scores in the MAAS are associated with a greater satisfaction with life (r = .88, p< .01 [95%CI: .85, .95]) and less depression (r = −.56, p< .01 [95%CI: −.48, −.77]) in older adults. Conclusions: The preliminary results back the use of the MAAS-5 as a self-report measure of mindfulness that has an adequate unifactorial structure that is reliable and invariant across gender for measuring the full attention state in elderly Peruvians.

The objective of this study was to evaluate factors related to the mental health of Peruvian older adults during the COVID-19 pandemic. The study had a cross-sectional and observational design. A total of 274 older adults in Lima, Peru (M_age = 67.86) filled out a sociodemographic survey, the Coronavirus Anxiety Scale, Mental Health Inventory-5, Patient Health Questionnaire-2 item, and Generalized Anxiety Disorder Scale. A Structural Equation Model (SEM) was estimated to test an a priori model that relates the sociodemographic variables, COVID-19 Anxiety, psychological well-being, anxiety and depression. The model fit indices indicated a good fit to the data. The socio-demographic variables explained 23.8% of the variance of the COVID-19 Anxiety (R² = .238). Socio-demographic variables explained 50.5% of psychological well-being variance, 52% of anxiety and 46.9% of depression. Also, sex, work; being diagnosed with COVID-19; family member with COVID-19 diagnosis; and time of exposure to COVID-19 information had statistically significant effects psychological well-being, anxiety and depression. In conclusion, some sociodemographic characteristics and COVID-19 anxiety affect the psychological well-being, anxiety and depression. The findings may allow for a better understanding of the mental health of older adults during the COVID-19 pandemic and guide government responses to detect, anticipate and minimize its impact on the mental health of this population.

Surgical procedures for breast cancer treatment are commonly followed by pain. Clinical hypnosis has been shown to be effective in reducing pain during and after surgery, but most of the studies have used analogical scales, which only measure pain intensity. The aim of this study was to evaluate the effect of clinical hypnosis on pain intensity and its interference in daily activities in patients before and after mastectomy. The patients were evaluated using the Brief Pain Inventory. Forty patients were randomly assigned to an experimental or control group and evaluated 5 times: 1) baseline, 2) after clinical hypnosis session, 3) before surgery, 4) 1 day after surgery, and 5) 1 week after the surgery (follow-up). The results showed that after surgery the hypnosis group had a statistically significant reduction in pain intensity, less interference of pain with daily activities, sleep and life enjoyment compared with a control group. Clinical hypnosis may be recommended as a complementary treatment procedure for postmastectomy pain reduction and improving the quality of life of these patients.

This research was done to find if using maximum likelihood could reduce the Interactive Optimism Scale-Garcia to a new valid and reliable shorter version. There were 502 adults: 263 women and 239 men ( M_age = 34.67, SD = 12.27). It was used in confirmatory factor analysis. A four-item scale is obtained, having excellent goodness of fit: [χ²/ df = .609, GFI (Jöreskog and Sörbom’s Goodness-of-Fit Index) = .999, NFI (Normed Fit Index) = .999, CFI (Bentler’s Comparative Fit Index) = 1.000, RMSEA (Steiger–Lind root mean square error of approximation) = .000 (90% CI = .0001, .077); SRMR (standardized root mean square residual) = .007], as well as factorial invariance across sexes; the scale has good internal consistency (ω = .869, α = .858, ordinal α = .906). Brief Interactive Optimism Scale-G correlates significantly with self-esteem ( r = .779, p < . 01, 95% CI [.816, .736]), depression ( r = −.810, p < .01, 95% CI [.843, .772]), and psychopathy ( r = −.670, p < . 01, 95% CI [.723, .611]). In conclusion, Brief Interactive Optimism Scale-G is a good option for measuring optimism in Mexicans.

The Scale of Positive and Negative Experience (SPANE) aims to measure affect with high transcultural validity. The bifactor model is the best theoretical option to represent affective balance, although it is not typically used in validation studies. The objectives of this research were to test a bifactor model vis-à-vis the traditional model composed of two correlated factors, to prove its invariance across sexes, and to provide evidence of concurrent validity. A nonprobability sample composed of 600 Mexican students of psychology and medicine was recruit. One-group and multigroup confirmatory factor analyses were carried out. The SPANE and the scales selected to assess depression, perceived stress, and satisfaction with life were applied. The bifactor model showed better goodness-of-fit indices than the two correlated factors model: Δχ ² (11) = 121.436, p  <   .   001, Δχ ² /Δ df  =   11.04 > 5, Δ GFI  =   .034, Δ NFI  =   .025, Δ NNFI  =   .022, and Δ CFI  =   .023 >.01. The internal consistency for the general factor as well as for the factor of positive affect was excellent, whereas it was good for the factor of negative affect. The measurement model was valid across sexes. The general factor of affective balance had a very high correlation with depression, high with perceived stress, and medium with satisfaction with life. It is concluded that SPANE is reliable and shows evidence of validity among Mexican student of psychology and medicine, and the bifactor model is adequate to represent affective balance.
