Review
BACKGROUND
Surrogacy is a highly debated method mainly used for treating women with infertility caused by uterine factors. This systematic review summarizes current levels of knowledge of the obstetric, medical and psychological outcomes for the surrogate mothers, the intended parents and children born as a result of surrogacy.
METHODS
PubMed, Cochrane and Embase databases up to February 2015 were searched. Cohort studies and case series were included. Original studies published in English and the Scandinavian languages were included. In case of double publications, the latest study was included. Abstracts only and case reports were excluded. Studies with a control group and case series (more than three cases) were included. Cohort studies, but not case series, were assessed for methodological quality, in terms of risk of bias. We examined a variety of main outcomes for the surrogate mothers, children and intended mothers, including obstetric outcome, relationship between surrogate mother and intended couple, surrogate's experiences after relinquishing the child, preterm birth, low birthweight, birth defects, perinatal mortality, child psychological development, parent-child relationship, and disclosure to the child.
RESULTS
The search returned 1795 articles of which 55 met the inclusion criteria. The medical outcome for the children was satisfactory and comparable to previous results for children conceived after fresh IVF and oocyte donation. The rate of multiple pregnancies was 2.6-75.0%. Preterm birth rate in singletons varied between 0 and 11.5% and low birthweight occurred in between 0 and 11.1% of cases. At the age of 10 years there were no major psychological differences between children born after surrogacy and children born after other types of assisted reproductive technology (ART) or after natural conception. The obstetric outcomes for the surrogate mothers were mainly reported from case series. Hypertensive disorders in pregnancy were reported in between 3.2 and 10% of cases and placenta praevia/placental abruption in 4.9%. Cases with hysterectomies have also been reported. Most surrogate mothers scored within the normal range on personality tests. Most psychosocial variables were satisfactory, although difficulties related to handing over the child did occur. The psychological well-being of children whose mother had been a surrogate mother between 5 and 15 years earlier was found to be good. No major differences in psychological state were found between intended mothers, mothers who conceived after other types of ART and mothers whose pregnancies were the result of natural conception.
CONCLUSIONS
Most studies reporting on surrogacy have serious methodological limitations. According to these studies, most surrogacy arrangements are successfully implemented and most surrogate mothers are well-motivated and have little difficulty separating from the children born as a result of the arrangement. The perinatal outcome of the children is comparable to standard IVF and oocyte donation and there is no evidence of harm to the children born as a result of surrogacy. However, these conclusions should be interpreted with caution. To date, there are no studies on children born after cross-border surrogacy or growing up with gay fathers.

Review
This study systematically reviewed the evidence for personality as a correlate of body image. Electronic databases and reference lists were searched in May 2016 for studies reporting an association between at least one dimension of personality and at least one component of negative body image. Twenty-six studies (33 discrete samples) met inclusion criteria. Sixteen samples were coded as medium-high quality. The results indicated that negative body image was associated with higher levels of Neuroticism and lower levels of Extraversion. Agreeableness was not related to body image, and findings for Conscientiousness and Openness were indeterminate. After taking study quality into account, negative body image was also associated with lower levels of Conscientiousness. Neuroticism was associated with negative body image in both women and men. Sex moderation effects for Extraversion, Openness, and Conscientiousness were indeterminate. Large-sample, prospective studies of personality and body image are recommended.

Meta-Analysis Review
The aim of this systematic review and meta-analysis was to investigate the diagnostic, the dimensional mean-level, and rank-order stability of personality disorders (PDs) and PD criteria over time. EMBASE, PsycInfo, PubMed, and Web of Science were searched for peer-reviewed studies published in either English, German, or French between the first publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980 and December 20, 2022. Inclusion criteria were a prospective longitudinal study design, assessing the stability of PDs or PD criteria over at least two measurement occasions at least one month apart, and using the same assessment at baseline and follow-up. Effect sizes included proportion of enduring cases (i.e., diagnostic stability), test-retest correlations (i.e., dimensional rank-order stability), and within-group standardized mean differences (i.e., dimensional mean-level stability), based on the first and last available measurement occasion. From an initial pool of 1473 studies, 40 were included in our analyses, covering 38,432 participants. 56.7% maintained the diagnosis of any PD, and 45.2% maintained the diagnosis of borderline PD over time. Findings on the dimensional mean-level stability indicate that most PD criteria significantly decreased from baseline to follow-up, except for antisocial, obsessive-compulsive, and schizoid PD criteria. Findings on the dimensional rank-order stability suggested moderate estimates, except for antisocial PD criteria, which were found to be high. Findings indicated that both PDs and PD criteria were only moderately stable, although between study heterogeneity was high, and stability itself depended on several methodological factors.

Dimensional personality traits and alcohol treatment outcome: a systematic review and meta-analysis.Addiction (Abingdon, England) Aug 2017To identify dimensional personality traits associated with treatment outcome for patients with an alcohol use disorder (AUD). (Meta-Analysis)
Meta-Analysis Review
AIMS
To identify dimensional personality traits associated with treatment outcome for patients with an alcohol use disorder (AUD).
METHODS
Systematic review and meta-analysis of clinical trials and longitudinal studies of ≥ 8 weeks in patients receiving treatment for AUD, in which the association between personality dimensions and treatment outcome was reported. Primary outcomes were relapse and alcohol consumption measures. Treatment retention was a secondary outcome.
RESULTS
Eighteen studies, including 4783 subjects, were identified. Twelve studies used Cloninger's Temperament and Personality Questionnaire (TPQ) or Temperament and Character Inventory (TCI). Remaining studies used a broad range of other personality measures. Compared with non-relapsers, patients who relapsed had higher novelty-seeking [standardized mean difference in novelty-seeking score 0.28; 95% confidence interval (CI) = 0.12, 0.44], lower persistence (-0.30, 95% = CI -0.48, -0.12), lower reward dependence (-0.16, 95% CI = -0.31, -0.01) and lower cooperativeness (-0.23, 95% CI = -0.41, -0.04). Few studies reported on alcohol consumption outcomes, therefore findings for those outcomes were inconclusive. Lower novelty-seeking predicted better retention in treatment in two of three studies. Most studies reported findings only for those retained in treatment, and did not attempt to account for missing data; therefore, findings for the primary outcomes cannot be generalized to patients who dropped out of treatment. Studies using personality instruments other than the TCI or TPQ reported no consistent findings on the association between personality variables and treatment outcome.
CONCLUSIONS
Among patients receiving treatment for an alcohol use disorder, those who relapse during follow-up have higher novelty-seeking, lower persistence, lower reward dependence and lower cooperativeness than those who do not relapse.

Review
PURPOSE
To date, some empirical studies showed a link between personality factors and frailty. Nevertheless, a systematic review is lacking synthesizing the current evidence. Consequently, the purpose of this review was to fill this gap in knowledge based on observational studies.
MATERIALS AND METHODS
Three electronic databases (PubMed, PsycINFO, CINAHL) were searched. Moreover, a hand search was conducted. Observational studies focusing on the association between personality and frailty were included, whereas disease-specific studies were excluded. Data referring to methods, characteristics of the sample and key findings were extracted. The NIH tool was used to assess study quality/risk of bias. Two reviewers performed study selection, extracted the data and conducted the quality assessment.
RESULT
In sum, five (mostly longitudinal) studies were included in the final synthesis. Mainly based on large, nationally representative cohorts, these studies point to an association between personality and frailty. More precisely, they mainly point to a link between low conscientiousness as well as high neuroticism and increased frailty levels. The quality of the studies included was quite high.
CONCLUSIONS
This knowledge may assist in identifying individuals at risk for increased frailty levels (i.e., particularly individuals with low conscientiousness and high neuroticism). Efforts to increase conscientiousness and reduce neuroticism may assist in postponing frailty. Future studies are required to elucidate the underlying mechanisms.

Review
In addition to social and environmental factors, individual personality traits have intricately linked with maladaptive behaviour. Thus, the purpose of this article was to review the link between individual personality traits and criminality. A systematic review was conducted to obtain information regarding the link between individual personality traits with criminal behaviour in the Sage, Web of Science, APA PsycNet, Wiley Online Library, and PubMed databases. The results indicate that individual personality traits that contribute towards criminality are (i) psychopathy; (ii) low self-control; and (iii) difficult temperament. As an overall impact, the review is expected to provide in-depth understanding of the link between individual personality traits and criminality; hence, greater consideration will be given to the dimension of personality as a notable risk factor of criminal behaviour.

Review
This systematic review focuses on personality traits according to both the Five Factor Model and Cloninger Psychobiological Model in relation to treatment related outcome variables across all stages of clinical psychotic illness. Search of Pubmed and Psychinfo databases led to final inclusion of 65 studies, which were ranked on quality and analyzed according to the associations between personality and outcome. Main findings are that higher levels of Harm Avoidance and Neuroticism are associated with higher symptom levels, tendency towards passive coping, greater self-stigma, lower quality of life, and Harm Avoidance to higher suicidality. Higher levels of Extraversion and higher levels of Self-Directedness are associated with more preference for active coping, more intrinsic motivation and higher self-esteem. Higher Novelty Seeking is related to more substance use and aggression, in men specifically. On outcome of trauma, care consumption and duration of untreated illness no consistent associations with personality traits were found. Combined evidence from both personality models however reveals a consistent pattern of personality traits related to clinical outcome in psychotic disorder, which is discussed in a dimensional manner.

BACKGROUND
People with a history of complex traumatic events typically experience trauma and stressor disorders and additional mental comorbidities. It is not known if existing evidence-based treatments are effective and acceptable for this group of people.
OBJECTIVE
To identify candidate psychological and non-pharmacological treatments for future research.
DESIGN
Mixed-methods systematic review.
PARTICIPANTS
Adults aged ≥ 18 years with a history of complex traumatic events.
INTERVENTIONS
Psychological interventions versus control or active control; pharmacological interventions versus placebo.
MAIN OUTCOME MEASURES
Post-traumatic stress disorder symptoms, common mental health problems and attrition.
DATA SOURCES
Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1937 onwards); Cochrane Central Register of Controlled Trials (CENTRAL) (from inception); EMBASE (1974 to 2017 week 16); International Pharmaceutical Abstracts (1970 onwards); MEDLINE and MEDLINE Epub Ahead of Print and In-Process & Other Non-Indexed Citations (1946 to present); Published International Literature on Traumatic Stress (PILOTS) (1987 onwards); PsycINFO (1806 to April week 2 2017); and Science Citation Index (1900 onwards). Searches were conducted between April and August 2017.
REVIEW METHODS
Eligible studies were singly screened and disagreements were resolved at consensus meetings. The risk of bias was assessed using the Cochrane risk-of-bias tool and a bespoke version of a quality appraisal checklist used by the National Institute for Health and Care Excellence. A meta-analysis was conducted across all populations for each intervention category and for population subgroups. Moderators of effectiveness were assessed using metaregression and a component network meta-analysis. A qualitative synthesis was undertaken to summarise the acceptability of interventions with the relevance of findings assessed by the GRADE-CERQual checklist.
RESULTS
One hundred and four randomised controlled trials and nine non-randomised controlled trials were included. For the qualitative acceptability review, 4324 records were identified and nine studies were included. The population subgroups were veterans, childhood sexual abuse victims, war affected, refugees and domestic violence victims. Psychological interventions were superior to the control post treatment for reducing post-traumatic stress disorder symptoms (standardised mean difference -0.90, 95% confidence interval -1.14 to -0.66; number of trials = 39) and also for associated symptoms of depression, but not anxiety. Trauma-focused therapies were the most effective interventions across all populations for post-traumatic stress disorder and depression. Multicomponent and trauma-focused interventions were effective for negative self-concept. Phase-based approaches were also superior to the control for post-traumatic stress disorder and depression and showed the most benefit for managing emotional dysregulation and interpersonal problems. Only antipsychotic medication was effective for reducing post-traumatic stress disorder symptoms; medications were not effective for mental comorbidities. Eight qualitative studies were included. Interventions were more acceptable if service users could identify benefits and if they were delivered in ways that accommodated their personal and social needs.
LIMITATIONS
Assessments about long-term effectiveness of interventions were not possible. Studies that included outcomes related to comorbid psychiatric states, such as borderline personality disorder, and populations from prisons and humanitarian crises were under-represented.
CONCLUSIONS
Evidence-based psychological interventions are effective and acceptable post treatment for reducing post-traumatic stress disorder symptoms and depression and anxiety in people with complex trauma. These interventions were less effective in veterans and had less of an impact on symptoms associated with complex post-traumatic stress disorder.
FUTURE WORK
Definitive trials of phase-based versus non-phase-based interventions with long-term follow-up for post-traumatic stress disorder and associated mental comorbidities.

Meta-Analysis
OBJECTIVE
Conduct a systematic review and meta-analysis to evaluate levels of anger among substance users compared to non-user controls and to analyze the possible association between anger and psychoactive substance use (PSU).
METHODS
The procedures of this review followed the Meta-Analyzes of Observational Studies in Epidemiology (MOOSE) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Four electronic databases (MEDLINE, EMBASE, BIREME, PsycINFO) were searched.
RESULTS
Twelve studies were included in the meta-analysis; 10 used the State-Trait Anger Expression Inventory (STAXI) anger trait subscale and two used the Buss-Perry-Aggression Questionnaire (BPAQ) anger subscale. The sample included 2,294 users of psychoactive substances and 2,143 non-users, all male. The mean difference in anger scale scores between users and non-users was 2.151 (95%CI 1.166-3.134, p ≤ 0.00, inconsistency index [I2] = 98.83) standard deviations. Age and abstinence duration did not moderate the difference in anger between substance users and non-users.
CONCLUSION
Users of psychoactive substances had elevated anger scores compared to non-users, which represents a high risk of relapse. It is suggested that PSU treatment programs include intensive anger management modules, focusing on factors such as dealing with daily stressors, family conflicts, frustrations, and problems.

BACKGROUND
No systematic review exists synthesizing studies examining the association between personality factors and use of cancer screenings. Hence, the aim of this systematic review is to provide an overview of empirical findings from observational studies investigating the link between personality factors (in terms of agreeableness, conscientiousness, extraversion, neuroticism and openness to experience) and use of cancer screenings.
METHODS
Medline, PsycInfo and CINAHL were searched using predefined search terms. Observational studies examining the link between personality factors and use of cancer screenings using validated tools were included. Study selection, data extraction, and quality assessment were performed by two reviewers.
RESULTS
In total, n = 11 studies were included in our systematic review. There is mostly inconclusive evidence regarding the link between agreeableness, neuroticism, openness to experience and the use of cancer screenings. Clearer evidence was identified for an association between increased extraversion and an increased use of cancer screenings. Moreover, the majority of studies identified a link between increased conscientiousness and an increased use of cancer screenings.
DISCUSSION
Studies indicate that personality factors, particularly an increased extraversion and increased conscientiousness, are associated with an increased use of cancer screenings. This knowledge may be beneficial to address individuals at risk for underuse.
