Anxiety symptoms in adolescents at risk for psychosis: a comparison among help seekers

Environmental and psychopathological predictors of clinical high-risk of psychosis in adolescence

OBJECTIVES

Clinical high-risk of psychosis (CHRp) samples can be heterogeneous, consisting essentially of people with not only psychotic-like experiences but also nonspecific symptoms that may reflect common mental disorders such as depression, anxiety, or substance abuse pathologies. Few studies have attempted to analyze and understand psychosis risk in relation to both environmental (ER) and psychopathological risk (PsR) factors. This study aimed to determine the clinical risk of psychosis in adolescents.

METHODS

A representative sample of 1824 Spanish adolescents from the general population was evaluated using different scales to thoroughly examine the possible interaction of CHRp with various ER and PsR factors. Partial correlations were calculated to assess the relationships between the variables. A series of hierarchical linear regression models were then used to obtain a CHRp predictor model.

RESULTS

The CHRp predictor model indicated that PsR was the most significant determining factor, explaining 22% of the total associated variance of CHRp. However, the ER factor also emerged as a significant predictor of high-risk psychosis (accounting for 9% of the variance).

CONCLUSIONS

A predictive model for CHRp in adolescents was found, in which common psychological problems were presented as more determinant risk factors than ER disruptors. Furthermore, certain transdiagnostic processes, such as psychological inflexibility, may play a central role in the development of mental health problems, including psychosis. Specifying the mechanisms underlying the emergence of CHRp in adolescence is the key to optimizing the focus of preventive therapeutic interventions in these early stages.

Factors impacting intent to seek treatment within youth at clinical high risk for psychosis

Existing work indicates that there is unmet need for care in those at clinical high risk (CHR) for psychosis. However, research on the factors that drive treatment seeking behaviors in this population is limited. Further, it is unknown how help-seeking behavior in CHR individuals compares to those seen in mood disorders, who have a higher rate of treatment seeking behavior. Participants (n = 559) completed an assessment of their intent to seek mental health treatment, attenuated psychosis-risk symptoms, and psychiatric symptoms and diagnoses. Participants were divided into CHR (n = 91), Mood Disorders (MD) (n = 72), or Community Controls (CC) groups (n = 396), whose intent to seek treatment was compared. Associations between intent to seek treatment with past treatment, depression, anxiety, positive and negative symptoms, distress from symptoms, intelligence quotient (IQ) estimates, and insight were assessed in CHR individuals. Further, it was assessed how this differs for the MD group. The MD group reported higher intent to seek treatment than CHR individuals, which reported higher intent to seek treatment than the CC group. In those at CHR, previous treatment, greater depression and anxiety severity, and higher distress all independently predicted higher intent to seek treatment. Depression predicted intent to seek treatment in both MD and CHR individuals. Previous treatment predicted intent to seek treatment in those at CHR. Our findings suggest that depression and past treatment utilization are critical factors in increasing intent to seek treatment in those at CHR, potentially serving as important targets for engaging this population in treatment.

Schematic beliefs, negative affect and paranoia in at-risk youth

OBJECTIVES

Attenuated symptoms of psychosis are a core feature of At-Risk Mental States. However, subthreshold levels of paranoia are also common among nonpsychosis populations. At present, little is known about whether the processes underpinning the experience of paranoid ideation in high-risk youth differ as a consequence of meeting At-Risk Mental States (ARMS) for psychosis criteria.

METHODS

This study utilized path analysis techniques to examine the relationships between schematic beliefs, negative affect and the experience of paranoia for two groups: a group meeting criteria for ARMS (n = 133) and a group presenting with emerging complex mental health difficulties who did not meet the criteria for ARMS (n = 137).

RESULTS

While the ARMS group displayed significantly greater maladaptive schematic beliefs and more severe symptomatology, the associations between schematic beliefs, symptoms of negative affect and paranoia did not differ as a consequence of ARMS status.

CONCLUSIONS

While meeting the ARMS criteria is associated with experiencing more maladaptive cognitions and more negative symptomatology among at-risk youth, the associations between these cognitive beliefs and symptoms may be similar for youth who do not meet ARMS. These findings have implications for broadening the scope of at-risk/high-risk and for developing effective interventions for young people presenting with emerging difficulties.

Schizotypy and help-seeking for anxiety

BACKGROUND

Delays in help-seeking for anxiety are common; however, earlier interventions improve long-term outcomes. This holds importance for high schizotypes since anxiety relates to psychotic symptom development. The study investigated whether schizotypal traits and anxiety itself influence help-seeking behaviour.

METHODS

A non-clinical student sample (N = 800) completed the Schizotypal Personality Questionnaire, Depression, Anxiety, Stress Scale and General Help-Seeking Questionnaire, vignette version online.

RESULTS

Recognizing another's help need was associated with lower anxiety scores. A trend was observed between lower schizotypy scores and better recognition of self-need for help. Actual help-seekers (N = 163) had significantly higher schizotypy and anxiety scores than non-help-seekers.

CONCLUSION

Schizotypal traits independently contribute to delays in help-seeking for anxiety. Approaching informal help sources whom also have anxiety symptoms can delay formal help-seeking, unless they have sought help themselves.

EPA guidance on the early intervention in clinical high risk states of psychoses

This guidance paper from the European Psychiatric Association (EPA) aims to provide evidence-based recommendations on early intervention in clinical high risk (CHR) states of psychosis, assessed according to the EPA guidance on early detection. The recommendations were derived from a meta-analysis of current empirical evidence on the efficacy of psychological and pharmacological interventions in CHR samples. Eligible studies had to investigate conversion rate and/or functioning as a treatment outcome in CHR patients defined by the ultra-high risk and/or basic symptom criteria. Besides analyses on treatment effects on conversion rate and functional outcome, age and type of intervention were examined as potential moderators. Based on data from 15 studies (n = 1394), early intervention generally produced significantly reduced conversion rates at 6- to 48-month follow-up compared to control conditions. However, early intervention failed to achieve significantly greater functional improvements because both early intervention and control conditions produced similar positive effects. With regard to the type of intervention, both psychological and pharmacological interventions produced significant effects on conversion rates, but not on functional outcome relative to the control conditions. Early intervention in youth samples was generally less effective than in predominantly adult samples. Seven evidence-based recommendations for early intervention in CHR samples could have been formulated, although more studies are needed to investigate the specificity of treatment effects and potential age effects in order to tailor interventions to the individual treatment needs and risk status.

Editorial: Co-occurring problems in children and adolescents - assessment and treatment issues

The scientific literature is replete with evidence of the high prevalence of co-occurring mental health problems in children, adolescents, and adults (e.g., Hawkins, ; Kessler et al., ; Oland & Shaw, ). Such empirical data are substantiated by therapist and clinician assessments of the presenting symptoms in their client populations. The take-away message from this scientific and practitioner work is clear: in the absence of effective prevention or intervention services, children and adolescents with co-occurring mental health problems are at heightened risk for a range of difficulties across multiple domains, including school failure, involvement in criminal activities, drug use, and poor social relationships. Whether at the symptomatic or diagnostic level, co-occurring mental health problems present significant challenges to traditional mental health treatment service delivery systems, in which individuals are often treated for their primary presenting disorder, but other potential mental health problems are not assessed or directly dealt with. Similarly, although there is evidence that mental health symptoms co-occur at high rates, the majority of research continues to focus on one mental health condition, to the neglect of comorbid problems.
