Parental alienation is a complicated, problematic, specialist area of mental health, family functioning, social policy and law. Child Attachment and Family Trauma Training (CAFTT) is committed to providing modern, professional grade training in attachment & neuropsychology, focusing on improving family functioning, professional practice, outcomes related to child development and family welfare. Attachment-Led Theory & Practice for Parental Alienation Parental alienation disrupts attachments, psycho-developmental prospects, and quality of life for hundreds of thousands of children and families.CAFTT's CPD accredited parental alienation training provides intensive, self-paced learning and multiple-choice assessment to achieve Certification in Attachment-Led Theory and Practice in Parental Alienation.PA1’s intensive and CPD-accredited parental alienation training updates typical approaches with modern attachment, family systems and neuropsychology. Parental alienation’s vulnerabilities, triggers, strategies, behaviours and incremental impacts on children's psychological functioning into adulthood are detailed across 16 lectures spanning 13.5 hours. The course critically and comparatively evaluates relevant law and practice. Evidence-based, trauma-informed and risk-based assessments are provided to assist resolution of cases, with effective professional and court management. Currently, there appears to be little or no other accredited, on demand training. PA1 is aimed at providing an empirically structured, open access route to understanding parental alienation and earning Continued Professional Development accreditation points in this complicated and specialist field.PA1 draws on the best practice and advice of some of the world’s top experts Years of interaction with the UK’s family court system corroborates the established observational literature with an aetiological perspective using updated attachment, neuropsychology and child development approaches.The process of alienation and its stages are explained in detail, alongside how each stage impacts on children and other family members. The incremental results for children and other family members are provided in short, medium and long-term form. The lectures are dual-designed as standalone references for a fully informed presentation on important topics, and to incrementally develop knowledge - not just of parental alienation but the various issues parents and professionals encounter when in the difficult position of facing, or being tasked to assist, where this type of parental manipulation may be ongoing. Parental alienation is one of many types of damaging parental manipulation, and often, the manipulation and persuasion of child professionals.Understanding the processes and results of parental alienation may raise awareness and identification of other types of abuse inflicted on children and concealed by manipulation of victims and professionals. Importantly, PA1 addresses, in detail, the pathogenesis of many mental health disorders arising from family interactions. Each lecture is arranged around addressing parental alienation as a mental health problem for the whole family unit, focusing on processes and outcomes for each family member.The course has more than 13.5 hours of intensive instruction across 16 lectures, making PA1 outstanding value for money. Obtaining the same level of knowledge from other sources would, we suggest, be far more time consuming and expensive. We offer the CPD version which has the same content as this open access version which has short CPD assessments after each lecture to gain Continues Professional Development Points. Please return to our homepage if you would prefer to purchase the CPD version which is  open to parents, families and professionals alike.

What is a Clinical Will? A clinical will is an arrangement is in place to manage closure of their clinical practice in the event of their serious illness, death, suspension, dismissal or other sudden clinical incapacity. Professional bodies are increasingly insisting on clinical wills being in place for all therapists as a condition of accreditation. What are the new BABCP Requirements on Clinical Wills and When do they start? As of 1 September 2023, all BABCP Accredited and Registered members will be required to ensure that an arrangement is in place to manage closure of their clinical practice in the event of their serious illness, death, suspension, dismissal or other sudden clinical incapacity. This means that either your employer will need to have appropriate arrangements and contingency plans in place, or that you have a formal Clinical Will document that provides instructions to an executor in the event that you are no longer able to continue practicing.  NB: This template is illustrative and for information and training purposes only and does not constitute or reflect legal advice. Your clinical will should be checked by legal or other professionals. This template is in no way endorsed by the BABCP.
