Mindful awareness as a mechanism of change for natural childbirth in pregnant women with high fear of childbirth: a randomised controlled trial.

BACKGROUND: Mindfulness-Based Childbirth and Parenting (MBCP) is effective in increasing natural childbirth in pregnant women with high fear of childbirth (FOC) as compared to enhanced care as usual (ECAU). We aimed to examine through which pathway of action MBCP reaches this effect, based on a model of approaching or avoiding the challenges related to childbirth. METHODS: One hundred eleven pregnant women with high FOC were measured pre- and post-intervention on FOC (emotion pathway), catastrophic beliefs about labour pain (cognition pathway) and mindful awareness (attention pathway). A multiple mediation model was used to examine through which pathway the mechanism of change operated in relation to approach (i.e., natural childbirth) versus avoidance (i.e., self-requested caesarean section). RESULTS: It was found that greater mindful awareness (18% R2 = 0.18, F[1107] = 22.77, p < 0.0001) was the only significant mechanism of change operating through the attentional pathway leading to natural childbirth. More specifically, nonreactivity to inner experience (a facet of mindful awareness) showed to be the strongest mechanism of change. More extensive meditation practice was positively associated with natural childbirth; however, the number of completed MBCP sessions was not associated with the outcome. CONCLUSIONS: An increase in mindful awareness was the strongest mechanism of change for better adaptation to the challenges of childbirth. Decreases in neither FOC nor catastrophic beliefs about labour pain were identified as mechanisms of change. Additionally, the more one meditated, the more one was inclined towards a natural childbirth. MBCP enhances adaptation to the challenges of childbirth and less use of obstetric interventions in the presence of high FOC. TRIAL REGISTRATION: The Netherlands Trial Register (NTR; 4302 ).

Fear of childbirth, nonurgent obstetric interventions, and newborn outcomes: A randomized controlled trial comparing mindfulness-based childbirth and parenting with enhanced care as usual.

OBJECTIVE: To investigate whether mindfulness-based childbirth and parenting (MBCP) or enhanced care as usual (ECAU) for expectant couples decreases fear of childbirth (FOC) and nonurgent obstetric interventions during labor and improves newborn outcomes. DESIGN: Randomized controlled trial. SETTING: Midwifery settings, the Netherlands, April 2014-July 2017. POPULATION: Pregnant women with high FOC (n = 141) and partners. METHODS: Allocation to MBCP or ECAU. Hierarchical multilevel and intention-to-treat (ITT) and per-protocol (PP) analyses. MAIN OUTCOME MEASURES: Primary: pre-/postintervention FOC, labor anxiety disorder, labor pain (catastrophizing and acceptance), and preferences for nonurgent obstetric interventions. Secondary: rates of epidural analgesia (EA), self-requested cesarean birth (sCB), unmedicated childbirth, and 1- and 5-minute newborn's Apgar scores. RESULTS: MBCP was significantly superior to ECAU in decreasing FOC, catastrophizing of labor pain, preference for nonurgent obstetric interventions, and increasing acceptance of labor pain. MBCP participants were 36% less likely to undergo EA (RR 0.64, 95% CI [0.43-0.96]), 51% less likely to undergo sCB (RR 0.49, 95% CI [0.36-0.67]), and twice as likely to have unmedicated childbirth relative to ECAU (RR 2.00, 95% CI [1.23-3.20]). Newborn's 1-minute Apgar scores were higher in MBCP (DM -0.39, 95% CI [-0.74 to -0.03]). After correction for multiple testing, results remained significant in ITT and PP analyses, except EA in ITT analyses and 1-minute Apgar. CONCLUSIONS: MBCP for pregnant couples reduces mothers' fear of childbirth, nonurgent obstetric interventions during childbirth and may improve childbirth outcomes. MBCP adapted for pregnant women with high FOC and their partners appears an acceptable and effective intervention for midwifery care.

Meditation or Medication? Mindfulness training versus medication in the treatment of childhood ADHD: a randomized controlled trial.

BACKGROUND: Attention-Deficit-Hyperactivity-Disorder (ADHD) is, with a prevalence of 5 %, a highly common childhood disorder, and has severe impact on the lives of youngsters and their families. Medication is often the treatment of choice, as it currently is most effective. However, medication has only short-term effects, treatment adherence is often low and most importantly; medication has serious side effects. Therefore, there is a need for other interventions for youngsters with ADHD. Mindfulness training is emerging as a potentially effective training for children and adolescents with ADHD. The aim of this study is to compare the (cost) effectiveness of mindfulness training to the (cost) effectiveness of methylphenidate in children with ADHD on measures of attention and hyperactivity/impulsivity. METHODS/DESIGN: A multicenter randomized controlled trial with 2 follow-up measurements will be used to measure the effects of mindfulness training versus the effects of methylphenidate. Participants will be youngsters (aged 9 to 18) of both sexes diagnosed with ADHD, referred to urban and rural mental healthcare centers. We aim to include 120 families. The mindfulness training, using the MYmind protocol, will be conducted in small groups, and consists of 8 weekly 1.5-h sessions. Youngsters learn to focus and enhance their attention, awareness, and self-control by doing mindfulness exercises. Parents will follow a parallel mindful parenting training in which they learn to be fully present in the here and now with their child in a non-judgmental way, to take care of themselves, and to respond rather than react to difficult behavior of their child. Short-acting methylphenidate will be administered individually and monitored by a child psychiatrist. Assessments will take place at pre-test, post-test, and at follow-up 1 and 2 (respectively 4 and 10 months after the start of treatment). Informants are parents, children, teachers, and researchers. DISCUSSION: This study will inform mental health care professionals and health insurance companies about the clinical and cost effectiveness of mindfulness training for children and adolescents with ADHD and their parents compared to the effectiveness of methylphenidate. Limitations and several types of bias that are anticipated for this study are discussed. TRIAL REGISTRATION: Dutch Trial Register: NTR4206 . Registered 11 October 2013.

'I've Changed My Mind', Mindfulness-Based Childbirth and Parenting (MBCP) for pregnant women with a high level of fear of childbirth and their partners: study protocol of the quasi-experimental controlled trial.

BACKGROUND: Approximately 25 % of pregnant women suffer from a high level of Fear of Childbirth (FoC), as assessed by the Wijma Delivery Expectancy Questionnaire (W-DEQ-A, score ≥66). FoC negatively affects pregnant women's mental health and adaptation to the perinatal period. Mindfulness-Based Childbirth and Parenting (MBCP) seems to be potentially effective in decreasing pregnancy-related anxiety and stress. We propose a theoretical model of Avoidance and Participation in Pregnancy, Birth and the Postpartum Period in order to explore FoC and to evaluate the underlying mechanisms of change of MBCP. METHODS/DESIGN: The 'I've Changed My Mind' study is a quasi-experimental controlled trial among 128 pregnant women (week 16-26) with a high level of FoC, and their partners. Women will be allocated to MBCP (intervention group) or to Fear of Childbirth Consultation (FoCC; comparison group). Primary outcomes are FoC, labour pain, and willingness to accept obstetrical interventions. Secondary outcomes are anxiety, depression, general stress, parental stress, quality of life, sleep quality, fatigue, satisfaction with childbirth, birth outcome, breastfeeding self-efficacy and cost-effectiveness. The total study duration for women is six months with four assessment waves: pre- and post-intervention, following the birth and closing the maternity leave period. DISCUSSION: Given the high prevalence and severe negative impact of FoC this study can be of major importance if statistically and clinically meaningful benefits are found. Among the strengths of this study are the clinical-based experimental design, the extensive cognitive-emotional and behavioural measurements in pregnant women and their partners during the entire perinatal period, and the representativeness of study sample as well as generalizability of the study's results. The complex and innovative measurements of FoC in this study are an important strength in clinical research on FoC not only in pregnant women but also in their partners.

Formal thought disorder in autism spectrum disorder predicts future symptom severity, but not psychosis prodrome.

Formal thought disorder (FTD) is a disruption in the flow of thought, which is inferred from disorganisation of spoken language. FTD in autism spectrum disorders (ASD) might be a precursor of psychotic disorders or a manifestation of ASD symptom severity. The current longitudinal study is a seven-year follow-up of 91 individuals aged 5-12 years with ASD. We tested (1) whether childhood FTD predicted prodromal symptoms of psychosis in adolescence and (2) whether childhood FTD was associated with greater ASD symptom severity in adolescence. ASD symptom severity was assessed in childhood (T1) and 7 years later (T2), using the autism diagnostic observation schedule (ADOS). At T1, the Kiddie-Formal Thought Disorder Rating Scale (KFTDS) was used to measure symptoms of FTD. At T2, the prodromal questionnaire (PQ) was used to assess prodromal symptoms of psychosis. FTD at T1 did not predict prodromal symptoms of psychosis at T2 in children with ASD. FTD symptoms at T1, namely illogical thinking, predicted ASD symptom severity at T2 and this effect remained significant after controlling for T1 ASD symptom severity. In children with ASD, illogical thinking predicts severity of ASD symptoms in adolescence, but FTD does not predict prodromal symptoms of psychosis.

Physical activity, mindfulness meditation, or heart rate variability biofeedback for stress reduction: a randomized controlled trial.

In contemporary western societies stress is highly prevalent, therefore the need for stress-reducing methods is great. This randomized controlled trial compared the efficacy of self-help physical activity (PA), mindfulness meditation (MM), and heart rate variability biofeedback (HRV-BF) in reducing stress and its related symptoms. We randomly allocated 126 participants to PA, MM, or HRV-BF upon enrollment, of whom 76 agreed to participate. The interventions consisted of psycho-education and an introduction to the specific intervention techniques and 5 weeks of daily exercises at home. The PA exercises consisted of a vigorous-intensity activity of free choice. The MM exercises consisted of guided mindfulness meditation. The HRV-BF exercises consisted of slow breathing with a heart rate variability biofeedback device. Participants received daily reminders for their exercises and were contacted weekly to monitor their progress. They completed questionnaires prior to, directly after, and 6 weeks after the intervention. Results indicated an overall beneficial effect consisting of reduced stress, anxiety and depressive symptoms, and improved psychological well-being and sleep quality. No significant between-intervention effect was found, suggesting that PA, MM, and HRV-BF are equally effective in reducing stress and its related symptoms. These self-help interventions provide easily accessible help for people with stress complaints.

Cost-Effectiveness of the Mindfulness-Based Childbirth and Parenting Program for Pregnant Women With Fear of Childbirth.

OBJECTIVE: To examine the cost-effectiveness of the Mindfulness-Based Childbirth and Parenting (MBCP) program compared with enhanced care as usual (ECAU). DESIGN: Randomized controlled trial. SETTING: Midwifery settings in the Netherlands, April 2014 to July 2017. PARTICIPANTS: Subset of pregnant women with high levels of fear of childbirth (N = 54: randomized to MBCP, n = 32, or to ECAU, n = 22) who were selected from the parent study because they completed all four cost questionnaires. METHODS: We measured self-reported health care and non-health care costs. A subset of participants from the parent study completed the questionnaires at all four assessment points. We used the Wijma Delivery Expectancy Questionnaire to measure fear of childbirth and used the EuroQol-5D to measure quality of life. We used these measures of effect together with societal costs in the primary cost-effectiveness analyses. In the secondary cost-effectiveness analyses, we used different estimates of effects and costs to test the robustness of the primary analyses. RESULTS: In all but one scenario, MBCP was more effective and cost less than ECAU. As indicated by the acceptability curves, the likelihood of MBCP being cost-effective varied within a range of 70% to 98%. CONCLUSION: Our findings indicate that MBCP is a cost-effective intervention to reduce fear of childbirth in pregnant women. Important next steps are to replicate the study in countries with different health care systems and to explore the potential for further integration of MBCP into midwifery care.

Examining an individualized, group-based social skills training using a mixed-methods design: A feasibility study.

Tailoring treatments to individual needs may be beneficial for treatment adherence and treatment effects. However, individualizing a group-based Social Skills Training (SST) may be complicated. Therefore, in this feasibility study, we examined outcomes after engagement in an individualized SST provided to 33 children aged 7-11 years (M = 9.39, SD = 1.09; 13 girls), who were referred to a mental health care center for various psychosocial problems. To analyze outcomes, we combined a top-down (including researcher-chosen measures: Questionnaires on pro-social, socially inadequate, and problem behavior) and a bottom-up (including participant-driven measures: Ratings of personal goals and evaluation reports) approach and used a mixed-methods design. After the SST, personal goals and pro-social behavior increased (large and small effects respectively). Also, socially inadequate behavior and problem behavior decreased (both small effects). Evaluation reports mainly showed improvements in social responsiveness, emotion regulation, and internalizing problems. At the same time, however, most parents also reported limitations (e.g., a lack of generalization). Altogether, we can conclude that (1) tailoring a group-based SST to the individual needs of children, as well as measuring progress on personal goals, is feasible and (2) mixed-method designs to study intervention effectiveness should be encouraged.

Self-Compassion and Anxiety in Adolescents with and without Anxiety Disorder.

Previous studies have linked self-compassion to mental health, specifically anxiety, in non-clinical adolescents, suggesting that self-compassion can be a protective factor against anxiety. This study compared the overall level of self-compassion and (un)compassionate self-responding in adolescents with and without an anxiety disorder and assessed the association between self-compassion and anxiety. This cross-sectional study included adolescents (12-19 years) with an anxiety disorder (N = 23) and a reference group (N = 28). Participants completed the Self-Compassion Scale (SCS) and State Trait Anxiety Inventory (STAI). Results showed that overall self-compassion and uncompassionate self-responding were significantly lower and higher in the clinical than the reference group, respectively, while compassionate self-responding did not differ between groups. In the clinical group, only uncompassionate self-responding was significantly associated with higher anxiety. In the reference group, uncompassionate self-responding showed a significant positive association with anxiety, and compassionate self-responding showed a significant negative association with anxiety. Although the results suggest that low uncompassionate self-responding may buffer against anxiety, the role of compassionate and uncompassionate self-responding remains unclear. An alternative explanation is that the uncompassionate self-responding items measure the presence of psychopathology in adolescents with an anxiety disorder. More research on the construct validity of the SCS uncompassionate self-responding scale is needed.

The Development and Validation of a Subscale for the School-Age Child Behavior CheckList to Screen for Autism Spectrum Disorder.

The first aim of this study was to construct/validate a subscale-with cut-offs considering gender/age differences-for the school-age Child Behavior CheckList (CBCL) to screen for Autism Spectrum Disorder (ASD) applying both data-driven (N = 1666) and clinician-expert (N = 15) approaches. Further, we compared these to previously established CBCL ASD profiles/subscales and DSM-oriented subscales. The second aim was to cross-validate results in two truly independent samples (N = 2445 and 886). Despite relatively low discriminative power of all subscales in the cross-validation samples, results indicated that the data-driven subscale had the best potential to screen for ASD and a similar screening potential as the DSM-oriented subscales. Given beneficial implications for pediatric/clinical practice, we encourage colleagues to continue the validation of this CBCL ASD subscale.

The association between formal thought disorder and finger print asymmetry in children with a psychiatric disorder: an exploratory study.

Dermatoglyphics are the ridge constellations found on the hand palms and foot soles that are permanently formed by the 24th week of pregnancy. Associations have been found between adult schizophrenia and irregularities and asymmetries in dermatoglyphics. Children have not been studied before. The aim of this study was to assess the association between formal thought disorder (FTD), as a possible forerunner of schizophrenia, in children and asymmetry or discordance (DISC) of the finger prints. 222 children, aged 6-14, from an outpatient department of child psychiatry participated. Finger prints were rated with the three-pattern system (whorls, loops or arches). FTD criteria were illogical thinking (ILL), loose associations (LA), incoherence (INC), and poverty of content of speech (POC), as rated by the clinician. When boys with and without DISC were compared, no differences in FTD were found. In contrast, however, girls with DISC showed significantly more FTD than girls without DISC, t (72) = -2.39, p = 0.02. Further, for boys, only total FTD was positively correlated with DISC of the middle finger, r = 0.20, p = 0.02. For girls, total FTD was positively correlated with DISC of the index finger: r = 0.30, p = 0.02; DISC of the middle finger: r = 0.27, p = 0.03; and with total DISC dichotomous: r = 0.27, p = 0.02. In addition, total DISC correlated positively with ILL: r = 0.31, p = 0.01; LA: r = 0.23, p = 0.05; INC: r = 0.30, p = 0.01; and total FTD: r = 0.31, p = 0.01. Overall, the existence of finger print discordance, as a possible marker of prenatal instability, was associated with the occurrence of FTD in girls.

Social skills training in children with PDD-NOS: an exploratory study.

OBJECTIVE: A deficit in social interaction is characteristic for children with Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS). The aim of this exploratory study is to assess the effect of Social Skills Training (SST) in children with DSM-IV based PDD-NOS. METHODS: Ten consecutively referred children (n = 3 girls and n = 7 boys, mean age = 8.5, mean Full Scale Intelligence Quotient [FSIQ] = 104) participated in the standardized SST in a university outpatient department of child psychiatry. The valid and reliable Children's Social Behaviour Questionnaire (CSBQ) and Self-Perception Profile for Children (SPPC) were filled out pre- and post treatment by parents and children respectively. RESULTS: Parent's CSBQ total and subscale "Social understanding" scores were significantly lower after the SST. Children's scores on the subscale "Scholastic Competence" of the SPPC were significantly higher after SST, whereas their scores on the SPPC subscale "Physical Appearance" were significantly lower after SST as compared to before. CONCLUSIONS: This study provides a first indication of positive effects of SST in children with PDD-NOS.

Can a simple assessment of fear of childbirth in pregnant women predict requests and use of non-urgent obstetric interventions during labour?

OBJECTIVE: To examine whether the Wijma Delivery Expectation Questionnaire (W-DEQ-A) and the one-item Fear of Childbirth-Postpartum-Visual Analogue Scale (FOCP-VAS) - measuring high FOC - are useful tools in predicting requested and received non-urgent obstetric interventions in pregnant women. DESIGN: A prospective cohort study. POPULATION AND SETTING: Self-selected pregnant women from midwifery care settings (n=401). METHODS: W-DEQ-A and FOCP-VAS were assessed at two timepoints in pregnancy. Measures of non-urgent obstetric interventions which were derived from medical files were: induction of labour, epidural analgesia, augmentation with oxytocin due to failure to progress and self-requested caesarean section. Hierarchical logistics regression models were used. MAIN OUTCOME MEASURES: The change in the Nagelkerke R2 was examined for three models predicting two outcome measures: (1) explicitly requested non-urgent obstetric interventions during pregnancy and (2) received non-urgent obstetric interventions during labour. The first model only included participants' characteristics, the second model also included FOCP-VAS ≥5, and in the third model the W-DEQ-A ≥66 was added. RESULTS: High FOC measured with FOCP-VAS≥5 predicted requested (pseudo-R2=0.33, X2=59.82, P<0.001) and received non-urgent obstetric interventions (pseudo-R2=0.19, X2=32.81, P<0.001) better than high FOC measured with W-DEQ-A≥66. CONCLUSION: This study is the first evaluating self-reported FOC and postpartum based on VAS (subjective outcome) in relation to actual pregnancy and childbirth outcomes derived from medical files (objective outcome). Non-urgent obstetric interventions could already be predicted in the first half of pregnancy by means of a simple FOC assessment with the one-item FOCP-VAS. Implementing this easy to use one-item screening tool in midwifery care is suggested.

Brief Report: Mindfulness Training for Chinese Adolescents with Autism Spectrum Disorder and Their Parents in Hong Kong.

This study investigated the feasibility and preliminary effectiveness of a concurrent mindfulness program (MYmind) on Chinese adolescents with autism spectrum disorder and their parents in Hong Kong, China using a randomized controlled trial with a waitlist control group. Results showed the study had 80% compliance rate, 0% dropout rate, and 89% response rate. Between-group comparisons showed mindfulness had trend effects on parent's rumination (g = 1.16), mindful parenting (d = 0.6), parenting style (d = 0.59), and parenting stress (d = 0.5). The study demonstrated the feasibility of the MYmind program in the Chinese context. A larger trial with longer follow-up period is suggested to better examine the effect of mindfulness on adolescents with ASD and their parents.

Attention in Children With Autism Spectrum Disorder and the Effects of a Mindfulness-Based Program.

Objective: Children with autism spectrum disorder (ASD) show atypical attention. Mindfulness-based programs (MBPs), with self-regulation of attention as a basic component, could benefit these children. Method: We investigated how 49 children with ASD differed from 51 typically developing (TD) children in their attention systems; and whether their attention systems were improved by an MBP for children and their parents (MYmind), using a cognitive measure of attention, the Attention Network Test. Results: Children with ASD did not differ from TD children in the speed of the attention systems, but were somewhat less accurate in their orienting and executive attention. Also, MYmind did not significantly improve attention, although trend effects indicated improved orienting and executive attention. Robustness checks supported these improvements. Conclusion: Trend effects of the MBP on the attention systems of children with ASD were revealed, as well as minor differences between children with ASD and TD children in their attention systems.

Mindful2Work the next steps: Effectiveness of a program combining physical exercise, yoga and mindfulness, adding a wait-list period, measurements up to one year later and qualitative interviews.

BACKGROUND: Mindful2Work is a 6-week program combining physical activity, yoga and mindfulness meditations, targeting (work-related) stress complaints from a body-mind perspective. MATERIALS AND METHODS: We combined a top-down approach (researcher-driven outcome measures) with a bottom-up approach (personal goals and interview data) to investigate the effects on 98 employees with at least moderate (work-related) stress. Effects on personal goals, well-being (stress, anxiety, depression, sleep, affect, happiness), functioning at work (dropout, mental and physical workability, work satisfaction), and training-specific aspects (mindful awareness, self-compassion, emotion regulation strategies) were assessed. RESULTS: Nearly all measures showed no change during the wait-list period, with only negative affect and physical workability showing small statistically significant improvements. Medium to large effect size improvements directly after training and at all follow-ups were found on primary outcomes stress (0.62-1.17), and risk for dropout from work (0.55-1.00), and largest effects occurred on personal goals (0.98-1.46). Improvements in well-being and functioning at work were medium directly after training, and at follow-up 1 (six weeks later) and 2 (six months later), and large at follow-up 3 (one year later). The training-specific measures showed small to medium effects after training and at follow-up 1. Further, from the interviews (n = 9), two main categories of effects emerged: well-being and acquired insights. CONCLUSION: Mindful2Work showed substantial and long-lasting improvements according to researcher-driven measures as well as participants' own reports.

Mindfulness-Based Program for Children with Autism Spectrum Disorder and Their Parents: Direct and Long-Term Improvements.

A combined mindfulness-based program for children and their parents (MYmind) was beneficial for adolescents with autism spectrum disorder (ASD). In this study, we investigated whether this program is also beneficial for younger children with ASD, whether effects last on the long-term, and whether it reduces common comorbid problems. Forty-five children referred with ASD aged 8 until 19 years old, and their parents participated. Repeated measures of children's and parents' social communication problems, emotional and behavioral functioning, mindful awareness, and of parenting were conducted pre-intervention, post intervention, 2-month follow-up, and 1-year follow-up. While children did not report significant changes in mindful awareness, their social communication problems decreased, and their emotional and behavioral functioning improved. Results were not consistent at each occasion; improvements reported by children were most substantial at a 2-month follow-up and only partly remained at a 1-year follow-up, while all children's improvements as reported by parents were present on all occasions. Parents themselves reported improved emotional and behavioral functioning, improved parenting, and increased mindful awareness on all occasions. Parents' social communication problems reduced only directly after the intervention. Most improvements were supported by the qualitative investigation of children's and parents' experienced change as reported on open-ended questions. This study suggests that children, including adolescents, with ASD and their parents can benefit from a mindfulness-based program with parallel sessions for children and parents.

High rates of psychiatric co-morbidity in PDD-NOS.

Rates of co-morbid psychiatric conditions in children with Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) are hardly available, although these conditions are often considered as more responsive to treatment than the core symptoms of PDD-NOS. Ninety-four children with PDD-NOS, aged 6-12 years were included. The DISC-IV-P was administered. At least one co-morbid psychiatric disorder was present in 80.9% of the children; 61.7% had a co-morbid disruptive behavior disorder, and 55.3% fulfilled criteria of an anxiety disorder. Compared to those without co-morbid psychiatric disorders, children with a co-morbid disorder had more deficits in social communication. Co-morbid disorders occur very frequently in children with PDD-NOS, and therefore clinical assessment in those children should include assessment of co-morbid DSM-IV disorders.

Multiple complex developmental disorder delineated from PDD-NOS.

The objective of this study was to identify behavioral differences between children with multiple complex developmental disorder (MCDD) and those with pervasive developmental disorder-not otherwise specified (PDD-NOS). Twenty-five children (6-12 years) with MCDD and 86 children with PDD-NOS were compared with respect to psychiatric co-morbidity, psychotic thought problems and social contact problems using the child behavior checklist/4-18, the Dutch version of the diagnostic interview schedule for children-Version IV, the child and adolescent functional assessment scale, and the autism diagnostic observation schedule-generic. MCDD was associated with anxiety disorders, disruptive behavior, and psychotic thought problems. PDD-NOS was associated with deficits in social contact. MCDD differs from autistic disorder, and can also be delineated from PDD-NOS.

Assessment of formal thought disorder: The relation between the Kiddie Formal Thought Disorder Rating Scale and clinical judgment.

The presence of formal thought disorder (FTD) in childhood is sometimes viewed as a possible precursor of psychotic symptoms or adult schizophrenia. It is possible to assess FTD in childhood in a valid and reliable manner, by using the Kiddie Formal Thought Disorder Rating Scale (K-FTDS). However, training and rating procedures are very time consuming, and may be particularly difficult during clinical assessment. The aim of this study was therefore to compare the clinician's rapid judgment of FTD to the detailed ratings of the K-FTDS. The K-FTDS was administered to 172 consecutively referred children, aged 6 to 12 years and subsequently rated by two blind raters. The same criteria, as used in the K-FTDS (illogical thinking, loose associations, incoherence, and poverty of content of speech), were rated by nine clinicians. The overall agreement between K-FTDS scores and FTD scores as rated by the clinician was low. The clinician's judgment of FTD did not correspond very highly with ratings on the K-FTDS. Thus, although detecting FTD has important clinical value, the assessment of its presence or absence seemed to depend highly on which measure was used.
