Typology of Parent-to-Child Emotions: A Study of Japanese Parents of a Foetus up to a 12-Year-Old Child.

Background: Emotions are the fundamental origin of parent-child bonding, which is measurable by the Scale for Parent-to-Child Emotions (SPCE) based on the theories of basic and self-conscious emotions. Methods: This study is based on the data from a cross-sectional study that we previously reported. The data consist of fathers and mothers who had a child/children, whose eldest child's age was at the foetal stage up to 12 years old, and were recruited via the Internet (N = 4600). A series of cluster analyses using factor scores (theta[Ó¨]s) of all domains of the SPCE were conducted. After the clusters emerged, the fathers and mothers allocated to each cluster were compared by the child's age stage. The validation of the classifications was also conducted using ANOVAs and chi-squared tests. A discriminant function analysis was conducted. Results: The participant mothers and fathers were classified into Cluster 1 (Lack of Bonding Emotions, n = 509), Cluster 2 (Bonding Disorder, n = 1471), Cluster 3 (Ambivalent Bonding Emotions, n = 1211), and Cluster 4 (Positive Bonding, n = 1409). Across the four clusters, there were no differences in the age of the parents or the gender of the child. During the second trimester, mothers made up the majority of Cluster 4 (Positive Bonding), totalling 81 cases (37.5%), whereas fathers made up the majority of Cluster 2 (Bonding Disorder), totalling 126 cases (60.0%). The three linear discriminants (LDs) well predicted the four clusters, and their functions showed cross validation. Conclusions: The typology of the SPCE is helpful to understand individual differences in terms of parental emotional bonding.

Tokophobia: Psychopathology and Diagnostic Consideration of Ten Cases.

Tokophobia is regarded as the intensive fear of childbirth that some pregnant women have. However, little is known about the psychopathological details of tokophobia (fear of childbirth). Between 2020 and 2021, a total of 10 pregnant women (nine nulliparae and one multipara) with a strong fear of childbirth were referred by obstetricians. Semi-structured psychopathological interviews were conducted, and two cases were judged to have obsession, three an overvalued idea, and one secondary delusion. Three were characterised by both obsession and overvalued idea and one by both obsession and secondary delusion. In total, six cases had features of an overvalued idea. All of the participants except one had a lifetime history of a specific phobia. In addition, their history included social phobia in two cases, panic disorder in one case, obsessive-compulsive disorder (other than tokophobia) in two cases, depressive disorder in two cases, bipolar disorder in two cases, and PTSD in six cases. To conclude, this study showed that tokophobia was not a phobic disorder but a kind of overvalued idea that requires specific assessment and treatment.

A scale of parent-to-child emotions: Adaptation, factor structure, and measurement invariance.

Emotions that parents feel when they think about their own child are extremely important in determining parenting approaches toward a child. Parental emotions should be defined under the rubric of human emotions that include both basic and self-conscious emotions. The Scale for Parent-to-Baby Emotions (SPBE) was developed underlying this concept, whereas an applicable scale for parent-to-child emotions for a wider age range for both mothers and fathers is needed. This study is aimed at examining the measurement invariance of this adapted scale among Japanese families. In a cross-sectional internet survey, men and women who had a child/children (including a fetus), whose eldest was aged up to 12 years old (N = 4600), were recruited. The questionnaire, which included the Scale for Parent-to-Child-Emotions-62 (SPCE-62) created from the SPBE via a process of rigorous translation, focused only on the eldest child. The feasibility of the SPCE-62 was assessed by a panel of three researchers. Each domain of both basic and self-conscious emotions was examined both in terms of robust factor structure and stable measurement invariance by multi-group confirmatory factor analysis. Responses to individual items were examined via item response theory, including differential item functioning. This resulted in a 43-item SPCE consisting of 9 domains: Happiness (four items), Anger (six items), Fear (four items), Sadness (five items), Disgust (five items), Shame (five items), Guilt (seven items), Alpha Pride (three items), and Beta Pride (four items). An empirical construct of parental emotion toward a child was derived. The SPCE makes it possible to measure parent-to-child emotions across parents' gender and the three age ranges of the child.

Is Your Pregnancy Unwanted or Unhappy? Psychological Correlates of a Cluster of Pregnant Women Who Need Professional Care.

BACKGROUND: A negative response towards a current pregnancy consists of two elements: unwantedness of and unhappiness about the current pregnancy. Little is clear about whether pregnant women can be categorized in terms of unwantedness and unhappiness as well as what the correlates are of these categories. METHODS: An internet survey of 696 women in their first trimester of pregnancy examined the participants' intention of and emotional reaction towards pregnancy, borderline personality traits, adult attachment style, depression, fear of childbirth, obsessive-compulsive symptoms, fetal bonding disorder, avoidance of taking part in child care, and consideration about termination of pregnancy (TOP). About one third of the participants were followed up with in their second trimester. RESULTS: Two-step cluster analysis using the participants' intention of and emotional reaction towards pregnancy revealed three groups of pregnant women: those who wanted and were happy about the pregnancy (Cluster 1), those who were unhappy about the pregnancy (Cluster 2), and those who did not intend to be pregnant but were happy about pregnancy (Cluster 3). Cluster 2 women, but not Cluster 3 women, were likely to be single, with borderline personality traits as well as unstable adult attachment styles, accompanied by depression, fear of childbirth, obsessive-compulsive symptoms, and fetal bonding disorder. They were more likely to avoid caring for the baby after childbirth and consider TOP. CONCLUSION: Expectant women who were unhappy about their pregnancy were at risk of psychological adjustment and need specific perinatal mental health assessment and care.

Tokophobia: Case Reports and Narratives of Ten Japanese Women.

Intense fear of childbirth by expectant women is called tokophobia. Because there are no qualitative studies targeting women with an intense fear of childbirth in Japan, it is unknown whether there is any link between the type of fear of objects/situations among tokophobic women and their psychological/demographic background. Furthermore, there is no available summary of the lived experience of Japanese women with tokophobia. This study aims to identify the intensity patterns of various types of fear among the participants and summarize the lived experience of having intense fear of childbirth. A qualitative descriptive study was conducted using a semi-structured interview. Pregnant women with an intense fear of childbirth participated in individual interviews facilitated by a psychiatrist and a midwife. Audio recordings of the interviews were transcribed and analyzed using a content analysis approach. The number of participants was ten. The types of feared objects varied individually and these were categorized as being related to either prospective or retrospective fear. The participants' experiences were grouped into three categories: difficulty in daily life, preoccupied negative expectation towards childbirth, and psychological adaptation to the upcoming childbirth. The results imply that women with tokophobia continuously suffer from fear in their daily life; hence, a special approach is needed to detect and reduce their fear.

A Scale of Parent-to-Child Emotions (SPCE): Development and validation of a short form.

Aim: Parents' emotions towards a child are extremely important. The Scale of Parent-to-Child Emotions (SPCE) consists of five basic and four self-conscious emotion domains for assessment of parental emotional states. Abridgement of the SPCE is needed for research and clinical settings. Methods: Our previous investigational data for SPCE development were used in this study. The sample of 2336 fathers and 2264 mothers, whose eldest child's age was up to 12 years old, was analyzed. Total information for each pair (form) of items corresponding to a latent trait (θ) was calculated. The form with the greatest amount of total information was selected as the best for each domain. In addition, relative efficiency for each form and correlations of raw sum scores in classical test theory (CTT) for short forms with factor scores in item response theory (IRT) were calculated. Results: The SPCE was shortened to 18 items by selecting two items each for nine domains. Correlations of raw sum scores in CTT for short forms with factor scores in IRT were correlated strongly and significantly. Conclusion: This abridged form of the scale, the SPCE-18, may be applicable in a busy clinical setting or research works to investigate the trajectory of parent-to-child emotions across a long span of time.

The Current Concept of Paternal Bonding: A Systematic Scoping Review.

Bonding is crucial to perinatal mental health. Despite an extensive body of literature on maternal bonding, few studies have focused on paternal bonding. This scoping review aimed to clarify the current state of the concept of paternal-infant/fetus bonding. The eligibility criteria were drawn from the population concept and context elements to answer the following questions: "what is paternal bonding?" and "what are the constructs of the concept of paternal bonding?" The review comprised 39 studies. Paternal bonding was associated with both positive and negative paternal behavior and thought and may be determined based on fathers' beliefs and rearing history. Most studies showed that father-child interaction is one of the factors promoting paternal bonding. However, fathers generally felt more distant from their babies post-delivery than mothers. Only a few studies originally defined paternal bonding; most relied on the definitions of maternal bonding. We found different descriptions lacking consensus. Few studies examined the differences between paternal and maternal bonding. No consensus exists on the concept, constructs, and assessment of paternal bonding. The causal relationship between paternal bonding and other variables is unexplored. Future studies should explore fathers' perspectives and experiences, focusing on the unknown aspects of paternal bonding identified in this review.

Development of a Scale for COVID-19 Stigma and Its Psychometric Properties: A Study among Pregnant Japanese Women.

Background: Stigma towards COVID-19 may negatively impact people who suffer from it and those supporting and treating them. Objective: To develop and validate a scale to assess 11-item COVID-19−related stigma. Methods: A total of 696 pregnant women at a gestational age of 12 to 15 weeks were surveyed using an online survey with a newly developed scale for COVID-19 stigma and other variables. The internal consistency of the scale was calculated using omega indices. We also examined the measurement invariance of the scale. Results: Exploratory factor analyses (EFAs) of the scale items were conducted using a halved sample (n = 350). Confirmatory factor analyses (CFAs) among the other halved sample (n = 346) compared the single-, two-, three-, and four-factor structure models derived from the EFAs. The best model included the following three-factor structure (χ2/df = 2.718, CFI = 0.960, RMSEA = 0.071): Omnidirectional Avoidance, Attributional Avoidance, and Hostility. Its internal consistency was excellent (all omega indices > 0.70). The three-factor structure model showed configuration, measurement, and structural invariances between primiparas and multiparas, and between younger (less than 32 years) and older women (32 years or older). Fear of childbirth, mother−fetal bonding, obsessive compulsive symptoms, depression, adult attachment self-model, and borderline personality traits were not significantly correlated with the Omnidirectional Avoidance subscale but correlated with the Attributional Avoidance and Hostility subscales (p < 0.001). Conclusion: The findings suggested that our scale for COVID-19 stigma was robust in its factor structure, as well as in construct validity.

Effects of 1-day e-learning education on perinatal psychological support skills among midwives and perinatal healthcare workers in Japan: a randomised controlled study.

BACKGROUND: Although midwives are expected to play a key role for psychological support throughout perinatal periods, their educational chances are limited. Versatile teaching strategies such as e-learning may be promising in expanding education. The objective of our study was to clarify the effects of an e-learning educational programme on midwives' empathic communication skills. METHODS: From April 2019 to September 2019, a randomised controlled trial of a 1-day e-learning educational programme on perinatal psychological issues (both perinatal mental health assessment and empathic communication) was conducted to improve empathic communication skills of midwives and perinatal healthcare workers. Two types of measurements (paper-and-pencil multiple-choice test and video-viewing tests of simulated patient) were used to measure the competency of empathic communication skills. RESULTS: Participants (N = 115) were randomly allocated to two groups (Intervention: n = 58, Control: n = 57). The intervention group was at a significantly higher level for both post-tests of empathic communication skills compared with the control group. Both intervention and control groups showed improvements in acquiring knowledge about perinatal mental health assessments. CONCLUSIONS: The results of our study show that a 1-day e-learning programme helped improve the midwives' empathic communications skills. Therefore, an effective 1-day e-learning educational programme of perinatal mental health will expand opportunity to learn about empathic communication skills for midwives and perinatal healthcare workers.

Factor Structure and Measurement Invariance of the Very Short Form of Infant Behavior Questionnaire-Revised (IBQR-VSF): A Study among Vietnamese Children.

The Infant Behavior Questionnaire-Revised (IBQ-R) assesses the temperament of infants in Western and non-Western countries. Although its factor analyses revealed three factors-surgency, negative affectivity, and effortful control-in the Western culture, the degree to which these are universal or culturally specific is unclear. This study developed a Vietnamese version of the IBQ-Revised Very Short Form (R-VSF) and examined its factor structure in a Vietnamese population. The Vietnamese IBQ-R VSF was administered to 292 mothers of infants between the ages of 3 and 18 months in Nha Trang city, Vietnam, between July and September 2019. After deleting items to achieve sufficient Cronbach's alphas for each scale (surgency, negative affectivity, and orienting/regulation), the remaining 28 items were aggregated to parcels subjected to exploratory factor analyses (EFAs). EFAs revealed a 3-factor model corresponding to the original theory, and confirmatory factor analyses indicated a good fit of this structural model. The final 3-factor model with parcels indicated measurement and structural invariance between mothers of boys and girls.

Prenatal and Intrapartum Factors Associated With Infant Temperament: A Systematic Review.

Background: Temperament involves individual variations in behavioural tendencies of emotional responses and reactions to stimuli after birth. Because 'foetal programming' is a strong hypothesis in developing temperament, prenatal and intrapartum factors may be significant determinants of infant temperament. This systematic literature review aims to elucidate the evidence of prenatal and intrapartum predictors, including genetic, biological, environmental, socio-demographic, psychological, and obstetric factors of parents and their child. Methods: Relevant articles were searched using MEDLINE, PubMed, and SCOPUS. The inclusion criteria were (a) original research article, (b) written in English, (c) assessed the temperament of infants 12 months old or younger as an outcome variable, and (d) investigated prenatal and intrapartum factorial variables of infant temperament. Following the PRISMA guideline, the articles found in the three databases were screened and selected according to the inclusion and exclusion criteria before the final review. Results: Finally, 35 articles were reviewed. This systematic review identified a variety of prenatal and intrapartum factors that were significantly associated with infant temperament: (1) genetic and biological factors: certain genotypes, maternal cortisol and ACTH, and CRHs, (2) environmental factors: substance use such as tobacco, alcohol, and illegal drugs, (3) socio-demographic factor: lower-income, (4) psychological factors: depression or anxiety, eating disorders, personality types of mothers, and domestic violence, and (5) obstetric factors: foetal growth (birth weight), hypertension in mothers, nausea (emesis), and preterm birth. Conclusion: The findings support gene-environment interaction and biological mechanisms for developing infant temperament, suggesting the importance of ensuring a safe and comfortable environment for pregnant mothers, unborn infants, and families during pregnancy and delivery.

Factor structure of the Postpartum Bonding Questionnaire: Configural invariance and measurement invariance across postpartum time periods.

BACKGROUND: Despite the research and clinical significance of the Postpartum Bonding Questionnaire (PBQ), its psychometric properties have not been studied intensively. The goodness-of-fit of proposed factor models of the PBQ is poor. Configural and measurement invariance have never been reported. METHODS: As a secondary analysis of the previous paper (Ohashi et al., 2016), we analysed the PBQ data at 5 days and 1 month after childbirth among 247 mothers of a singleton. We created 9 parcels of PBQ items to perform confirmatory factor analysis (CFA). We also examined configural and measurement invariances of the PBQ factor structure between the two observation times. RESULTS: The CFI of the 3-factor model of the PBQ was .936 and .968 for 5 days and 1 month after childbirth, respectively. Configural, measurement (metric, scalar, and residual), and structural (factor variance and factor covariance) invariances were accepted. The mean of only 'anger and restrictedness' factor was scored higher at 1 month than 5 days after childbirth. CONCLUSION: The 3-factor model of the PBQ was good in its fit with the data as well as robust in its measurement between the two observation time periods.

Cross-National Differences in Psychosocial Factors of Perinatal Depression: A Systematic Review of India and Japan.

Perinatal depression is prevalent worldwide. However, there are few available studies that discuss the different cultural factors affecting perinatal depression within Asian countries. This study aims to compare the literature regarding related factors relating to perinatal depression in India and Japan, and to synthesize the evidence common to both countries in addition to the country-specific evidence. We conducted a systematic review using several databases (CINAHL, MEDLINE, Pubmed, Ovid, SCOPUS, IndMED, and ICHUSI). Keywords were "antenatal depression" or "postpartum depression", and "India" or "Japan". Both Japanese and English language papers were reviewed. The identified evidence was compared between the two countries, as well as with non-Asian countries based on previous reports. In total, 15 articles on India and 35 on Japan were reviewed. Although several factors were shared between the two countries as well as with other non-Asian countries (vulnerable personality, being abused, age, marital conflict, and lower socio-demographic status), some differing factors were identified between India and Japan and non-Asian countries; India: poor socioeconomic status, living only with the husband, pregnancy not welcomed by the husband, a female baby, and poor relationship with in-laws; Japan: infertility treatment, conflict with work-life balance, poor relationships with biological mother or in-laws, and concerns about social relations with the other mother's friends. To conclude, involving the family and community may be important for implementing both global standardized and culture-specific interventions. In India, treatment involving the in-laws may be effective because large family structure is a significant predictor of perinatal depression. In Japan, a family/community approach involving not only the mother's family of origin but also the working environment is essential.

Postpartum Bonding Disorder: Factor Structure, Validity, Reliability and a Model Comparison of the Postnatal Bonding Questionnaire in Japanese Mothers of Infants.

Negative attitudes of mothers towards their infant is conceptualized as postpartum bonding disorder, which leads to serious health problems in perinatal health care. However, its measurement still remains to be standardized. Our aim was to examine and confirm the psychometric properties of the Postnatal Bonding Questionnaire (PBQ) in Japanese mothers. We distributed a set of questionnaires to community mothers and studied 392 mothers who returned the questionnaires at 1 month after childbirth. Our model was compared with three other models derived from previous studies. In a randomly halved sample, an exploratory factor analysis yielded a three-factor structure: Anger and Restrictedness, Lack of Affection, and Rejection and Fear. This factor structure was cross-validated by a confirmatory factor analysis using the other halved sample. The three subscales showed satisfactory internal consistency. The three PBQ subscale scores were correlated with depression and psychological abuse scores. Their test-retest reliability between day 5 and 1 month after childbirth was measured by intraclass correlation coefficients between 0.76 and 0.83. The Akaike Information Criteria of our model was better than the original four-factor model of Brockington. The present study indicates that the PBQ is a reliable and valid measure of bonding difficulties of Japanese mothers with neonates.

Disagreement between parents on assessment of child temperament traits.

BACKGROUND: Accuracy of temperament assessment is a prerequisite in research studies. To identify the extent to which parental assessment of child temperament is biased by their personal attributes, we proposed a new structural equation model, in which biases of parental attributes in their assessment of child temperament can be separated from the true (i.e. non-biased) associations between the two. METHODS: We examined 234 father-mother pairs using questionnaires including Emotionality, Activity, Sociability, and Impulsivity; Social Desirability Scale; Hospital Anxiety and Depression Scale; Temperament and Character Inventory; and State-Trait Anger Expression Inventory. RESULTS: Paternal Depression and Persistence, maternal Trait Anger, and parental Novelty Seeking showed significant bias in assessment of Emotionality. Maternal Self-transcendence showed significant bias in assessment of child Impulsivity. CONCLUSION: Researchers should be cautious about biases in parental assessment of children's Emotionality and Impulsivity, but other temperament traits may be free from such biases.

Temperament, Character, and Depressive Symptoms during Pregnancy: A Study of a Japanese Population.

Background. To examine the effects of temperament and character domains on depression during pregnancy. Methods. We examined 601 pregnant women using a questionnaire that included the Edinburgh Postnatal Depression Scale (EPDS), the Temperament and Character Inventory (TCI), and demographic variables. Results. In a hierarchical regression analysis, severity of depression during pregnancy was predicted by the women's negative response towards the current pregnancy, low self-directedness, and high harm avoidance, persistence, and self-transcendence. Conclusion. Depression during pregnancy is predicted by personality traits as well as women's negative attitudes towards the current pregnancy.
