Logics of public communications

Multi-modal versions of propositional logics S5 or S4—commonly accepted as logics of knowledge—are capable of describing static states of knowledge but they do not reflect how the knowledge changes after communications among agents. In the present paper (part of broader research on logics of knowledge and communications) we define extensions of the logic S5 which can deal with public communications. The logics have natural semantics. We prove some completeness, decidability and interpretability results and formulate a general method that solves certain kind of problems involving public communications—among them well known puzzles of Muddy Children and Mr. Sum & Mr. Product. As the paper gives a formal logical treatment of the operation of restriction of the universe of a Kripke model, it contributes also to investigations of semantics for modal logics.

5-HTTLPR、性别、家庭社会经济地位与面孔表情识别的关系

该研究采用531名中国汉族健康大学生为被试,综合考察了5-HTTLPR(5-羟色胺转运体基因连锁多态区)基因型、性别和家庭社会经济地位之间交互作用与面孔表情识别的关系。研究结果发现,性别和家庭社会经济地位在面孔表情识别上有显著的主效应。总体来说,家庭社会经济地位较高和女性的被试具有较好的面孔表情识别能力。5-HTTLPR基因型、性别、家庭社会经济地位,它们在面孔表情识别上的三因素交互作用也显著。该三因素交互作用主要是源于,在高家庭社会经济地位背景下,女性携带有5-HTTLPR长片段等位基因比短片段纯合子表现出稍差的面孔表情识别能力。该结果体现了基因与环境多因素交互作用对面孔表情识别能力的重要性。     

Integrity of Literature on Expressed Emotion and Relapse in Patients with Schizophrenia Verified by a p‐Curve Analysis

There is growing concern that much published research may have questionable validity due to phenomena such as publication bias and p‐hacking. Within the psychiatric literature, the construct of expressed emotion (EE) is widely assumed to be a reliable predictor of relapse across a range of mental illnesses. EE is an index of the family climate, measuring how critical, hostile, and overinvolved a family member is toward a mentally ill patient. No study to date has examined the evidential value of this body of research as a whole. That is to say, although many studies have shown a link between EE and symptom relapse, the integrity of the literature from which this claim is derived has not been tested. In an effort to confirm the integrity of the literature of EE predicting psychiatric relapse in patients with schizophrenia, we conducted a p‐curve analysis on all known studies examining EE (using the Camberwell Family Interview) to predict psychiatric relapse over a 9‐ to 12‐month follow‐up period. Results suggest that the body of literature on EE is unbiased and has integrity, as there was a significant right skew of p‐values, a nonsignificant left skew of p‐values, and a nonsignificant test of flatness. We conclude that EE is a robust and valuable predictor of symptom relapse in schizophrenia.     

Finer Distinctions: Variability in Satisfied Older Couples’ Problem‐Solving Behaviors

This study utilized observational and self‐report data from 64 maritally satisfied and stable older couples to explore if there were meaningful differences in how couples approached marital disagreements. Using a typology approach to classify couples based on their behaviors in a 15‐minute problem‐solving interaction, findings revealed four types of couples: (1) problem solvers (characterized by both spouses’ higher problem‐solving skills and warmth), (2) supporters (characterized by both spouses’ notable warmth), (3) even couples (characterized by both spouses’ moderate problem‐solving skills and warmth), and (4) cool couples (characterized by both spouses’ greater negativity and lower problem‐solving skills and warmth). Despite the differences in these behaviors, all couples had relatively high marital satisfaction and functioning. However, across nearly all indices, spouses in the cool couple cluster reported poorer marital functioning, particularly when compared to the problem solvers and supporters. These findings suggest that even modest doses of negativity (e.g., eye roll) may be problematic for some satisfied couples later in life. The implications of these typologies are discussed as they pertain to practitioners’ efforts to tailor their approaches to a wider swath of the population.     

Unreliable Bodies: A Follow‐up Twenty Years Later by a Mother and Daughter about the Impact of Illness and Disability on their Lives

We are a mother and daughter, both health care professionals, who offer a follow‐up to an article we published twenty years ago about the impact of each other's ongoing, serious medical problems on our relationship. In this article, we contribute a long‐term perspective on the differences between having an illness that is well or poorly understood by medical professionals and the lay community. We also discuss health in the context of identity formation and life stage, as during this interval the daughter left home, graduated college, married, and had two children. Also in this period, the mother survived a third breast cancer and other life‐threatening illnesses. We discuss the impact of these experiences on each other and in other important relationships in our lives. Current discourses on daughters of breast cancer survivors do not fit our experience and we speculate about why our story differs. We find that although we continue to contend with serious medical issues that impact our own, each other's, and our families' lives, nonetheless, our lives are rich, rewarding, and “appropriate” for our life stage. That is the news.     

Deployment‐Related Benefit Finding and Postdeployment Marital Satisfaction in Military Couples

Extensive research has evaluated potential negative effects of military deployments on romantic relationships. Comparatively few studies have examined potential positive effects of such deployments. In stressful situations, benefit finding (BF) has been found to be linked with better functioning on both individual and interpersonal levels. This study reports on deployment‐related BF in a sample of 67 male service members (SMs) who deployed at least once since 9/11/2001 and their wives. Couples completed measures of marital satisfaction at baseline (an average of 1 year postdeployment) and follow‐up 4–6 months later. At follow‐up, SMs also provided data on symptoms of posttraumatic stress, and both partners provided reports of deployment‐related BF. Multivariate path analysis controlling for SMs' PTSD symptom severity revealed that wives' BF was positively associated with increases in SMs' relationship satisfaction. These findings suggest that wives' responses to deployment may be more influential than SMs' responses to deployment on military couples' relationships. This pattern indicates that support for spouses during deployments is essential; furthermore, such support should include an emphasis on trying to facilitate personal growth in spouses.     

Caregiver Expressed Emotion and Psychiatric Symptoms in African‐Americans with Schizophrenia: An Attempt to Understand the Paradoxical Relationship

Expressed emotion (EE) is a family environmental construct that assesses how much criticism, hostility, and/or emotional over‐involvement a family member expresses about a patient (Hooley, Annual Review of Clinical Psychology, 2007, 3, 329). Having high levels of EE within the family environment has generally been associated with poorer patient outcomes for schizophrenia and a range of other disorders. Paradoxically, for African‐American patients, high‐EE may be associated with a better symptom course (Rosenfarb, Bellack, & Aziz, Journal of Abnormal Psychology, 2006, 115, 112). However, this finding is in need of additional support and, if confirmed, clarification. In line with previous research, using a sample of 30 patients with schizophrenia and their primary caregivers, we hypothesized that having a caregiver classified as low‐EE would be associated with greater patient symptom severity. We also aimed to better understand why this pattern may exist by examining the content of interviews taken from the Five‐Minute Speech Sample. Results supported study hypotheses. In line with Rosenfarb et al. (2006), having a low‐EE caregiver was associated with greater symptom severity in African‐American patients. A content analysis uncovered some interesting patterns that may help elucidate this finding. Results of this study suggest that attempts to lower high‐EE in African Americans may, in fact, be counterproductive.     

The Integration of Family and Group Therapy as an Alternative to Juvenile Incarceration: A Quasi‐Experimental Evaluation Using Parenting with Love and Limits

The current study employed a quasi‐experimental design using both intent‐to‐treat and protocol adherence analysis of 155 moderate‐ to high‐risk juvenile offenders to evaluate the effectiveness of Parenting with Love and Limits® (PLL), an integrative group and family therapy approach. Youth completing PLL had significantly lower rates of recidivism than the comparison group. Parents also reported statistically significant improvements in youth behavior. Lengths of service were also significantly shorter for the treatment sample than the matched comparison group by an average of 4 months. This study contributes to the literature by suggesting that intensive community‐based combined family and group treatment is effective in curbing recidivism among high‐risk juveniles.     

The Impact of Couple Therapy on Service Utilization among Military Veterans: The Moderating Roles of Pretreatment Service Utilization and Premature Termination

Couple therapy reduces relational and individual distress and may affect utilization of other health services, particularly among higher service utilizers. Although average decreases in service utilization are predicted among recipients of couple therapy, low utilizers of services may appropriately increase use. The relationship between couple therapy and service utilization was examined among a sample of 179 U.S. military veterans who received treatment in Veterans Affairs (VA) specialty couple therapy clinics. Consistent with hypotheses, overall mental and physical health visits decreased from the 12 months preceding couple therapy to the 12 months following treatment. Moderator analyses showed that decreases were greatest among individuals who were rated by their therapist as having completed a full course of couple therapy, suggesting that change was attributable to intervention. Pretreatment service utilization also moderated observed change—higher utilizers’ use of services decreased substantially, whereas lower utilizers’ slightly increased. Cost analyses revealed that the estimated per person mean cost in our sample decreased by $930.33 in the year following compared to the year prior to couple therapy, as per 2008 VA cost data. As service utilization data were only available for one partner and only for 1 year posttherapy, the true magnitude of this effect may be underestimated. Our findings are relevant to policy makers as they demonstrate that couple therapy reduces average service utilization and associated costs and addresses calls for analyses of cost effectiveness of systemic interventions.
