Does your mindfulness benefit others? A systematic review and meta‐analysis of the link between mindfulness and prosocial behaviour

Mindfulness‐based meditation practices have received substantial scientific attention in recent years. Mindfulness has been shown to bring many psychological benefits to the individual, but much less is known about whether these benefits extend to others. This meta‐analysis reviewed the link between mindfulness – as both a personality variable and an intervention – and prosocial behaviour. A literature search produced 31 eligible studies (N = 17,241) and 73 effect sizes. Meta‐analyses were conducted using mixed‐effects structural equation models to examine pooled effects and potential moderators of these effects. We found a positive pooled effect between mindfulness and prosocial behaviour for both correlational (d = .73 CI 95% [0.51 to 0.96]) and intervention studies (d = .51 CI 95% [0.37 to 0.66]). For the latter, medium‐sized effects were obtained across varying meditation types and intensities, and across gender and age categories. Preliminary evidence is presented regarding potential mediators of these effects. Although we found that mindfulness is positively related to prosociality, further research is needed to examine the mediators of this link and the contexts in which it is most pronounced.     

Evidence for a sensitive period in the effects of early life stress on hippocampal volume

Exposure to stress has been causally linked to changes in hippocampal volume (HV). Given that the hippocampus undergoes rapid changes in the first years of life, stressful experiences during this period may be particularly important in understanding individual differences in the development of the hippocampus. One hundred seventy‐eight early adolescents (ages 9–13 years; 43% male) were interviewed regarding exposure to and age of onset of experiences of stress; the severity of each stressful event was rated by an objective panel. All participants underwent structural magnetic resonance imaging, from which HVs were automatically segmented. Without considering the age of onset for stressful experiences, there was a small but statistically significant negative association of stress severity with bilateral HV. When considering the age of onset, there was a moderate and significant negative association between stress severity during early childhood (through 5 years of age) and HV; there was no association between stress severity during later childhood (age 6 years and older) and HV. We provide evidence of a sensitive period through 5 years of age for the effects of life stress on HV in adolescence. It will be important in future research to elucidate how reduced HV stemming from early life stress may contribute to stress‐related health outcomes.     

Which components of processing speed are affected in ADHD subtypes?

The term “processing speed” (PS) encompasses many components including perceptual, cognitive and output speed. Despite evidence for reduced PS in Attention-Deficit/Hyperactivity Disorder (ADHD), little is known about which component(s) is most impacted in ADHD, or how it may vary by subtypes. Participants included 151 children, ages 8–12 years, with ADHD Predominantly Inattentive Type, ADHD Combined Type and typically developing controls using DSM-IV criteria. All children completed four measures of processing speed: Symbol Search, Coding, Decision Speed, and simple reaction time. We found children with ADHD-PI and ADHD-C had slower perceptual and psychomotor/incidental learning speed than controls and that ADHD-PI had slower decision speed than controls. The subtypes did not differ on any of these measures. Mean reaction time was intact in ADHD. Hence, at a very basic output level, children with ADHD do not have impaired speed overall, but as task demands increase their processing speed becomes less efficient than controls’. Further, perceptual and psychomotor speed were related to inattention, and psychomotor speed/incidental learning was related to hyperactivity/impulsivity. Thus, inattention may contribute to less efficient performance and worse attention to detail on tasks with a higher perceptual and/or psychomotor load; whereas hyperactivity/impulsivity may affect psychomotor speed/incidental learning, possibly via greater inaccuracy and/or reduced learning efficiency. Decision speed was not related to either dimension. Results suggest that PS deficits are primarily linked to the inattention dimension of ADHD but not exclusively. Findings also suggest PS is not a singular process but rather a multifaceted system that is differentially impacted in ADHD.     

Teacher Gender and Nonverbal Behavior in the Teaching of Gender-Stereotyped Materials1

Twenty teachers each taught a male and a female student two different lessons. One of these lessons was in a stereotypically masculine domain (mechanics), the other in a stereotypically feminine domain (vocabulary). Judges viewed clips from the videotaped lessons and rated teachers' nonverbal behaviors. The students also rated their teachers on a variety of behavioral dimensions. The results showed that teachers exhibited more positive behavior toward the students for whose gender the material being taught was stereotypically appropriate. Similarly, teachers exhibited more negative behavior toward those students for whose gender the material being taught was considered stereotypically inappropriate. Additionally, teacher gender was shown to interact with the above-mentioned biased teaching behavior. Generally speaking, women teachers behaved in a less gender-biased way than did men teachers. It is suggested that these kinds of differential teaching behaviors may contribute to the differential performance of male and female students in traditionally gender-stereotyped academic domains.     

HYPERFEMININITY AND INFLUENCE

Murnen and Byrne (1991) have defined hyperfemininity as an exaggerated adherence to a feminine gender role as it relates to heterosexual relationships. Hyperfeminine women believe their success is determined by maintaining a romantic relationship with a man, and that their sexuality can be used to maintain this relationship. Extrapolating from theory concerning gender and status, including expectation states theory, it was hypothesized that a woman's expression of hyperfeminine attitudes would lead male college student participants to agree with her in response to a persuasive speech because it would indicate her compliance with women's subordinate status. It was found that men (but not women) who listened to a very hyperfeminine (high) speaker agreed with her more than did men who heard a mildly hyperfeminine (low) speaker, despite the fact that the high hyperfeminine speaker was judged less competent and knowledgeable. Implications of the results, including the idea that the sexual objectification of women perpetuates women's subordinate status, were discussed.     

How do I cope with pain? Let me count the ways: awareness of pain coping behaviors and relationships with depression and anxiety

Patients with chronic pain are often undertreated with medications alone and need alternative ways of coping. Identifying pain coping skills patients use may be beneficial; however, no research has investigated whether patients are aware of their coping skills. The purpose of this study was to determine whether patients are aware of their pain coping skills, whether certain patient characteristics were related to using coping strategies, and whether coping strategies were related to psychiatric symptoms. Chart reviews were conducted on seventy-eight chronic pain patients who completed a semi-structured psychological interview. Patients endorsed using more coping strategies on the measure compared to the verbal self-report. Identifying with certain patient demographics was related to higher use of some coping strategies. Symptoms of anxiety and depression were also related to the use of some coping strategies. Anxiety was negatively related to ignoring the pain and using self-talk coping statements and positively related to catastrophizing. Depression was negatively related to the use of distraction, ignoring the pain, and using self-talk coping statements. Depression and pain severity were both positively related to catastrophizing and prayer. Results suggest that clinicians may need to help patients become aware of adaptive coping strategies they already use and that the use of certain coping strategies is related to lower levels of depression and anxiety.     

Positive and negative mood following imaging-guided core needle breast biopsy and receipt of biopsy results

Positive and negative mood are independent psychological responses to stressful events. Negative mood negatively impacts well-being and co-occurring positive mood leads to improved adjustment. Women undergoing core needle breast biopsies (CNB) experience distress during CNB and awaiting results; however, influences of mood are not well known. This longitudinal study examines psychosocial and biopsy- and spirituality-related factors associated with mood in patients day of CNB and one week after receiving results. Ninety women undergoing CNB completed questionnaires on psychosocial factors (chronic stress, social support), biopsy experiences (pain, radiologist communication), and spirituality (peace, meaning, faith) day of CNB. Measures of positive and negative mood were completed day of CNB and one week after receiving results (benign n = 50; abnormal n = 25). Multiple linear regression analyses were conducted. Greater positive mood correlated with greater peace (β = .25, p = .02) day of CNB. Lower negative mood correlated with greater peace (β = ?.29, p = .004) and there was a trend for a relationship with less pain during CNB (β = .19, p = .07). For patients with benign results, day of CNB positive mood predicted positive mood post-results (β = .31, p = .03) and only chronic stress predicted negative mood (β = .33, p = .03). For women with abnormal results, greater meaning day of CNB predicted lower negative mood post-results (β = ?.45, p = .03). Meaning and peace may be important for women undergoing CNB and receiving abnormal results.
