All in the Mind

Claudia visits a specialist personality disorder clinic in South London where she meets Jo, Susan and Chanelle to talk about what it's like to have a diagnosis of borderline personality disorder. Psychotherapist, Merryn Jones explains why long term, regular group and individual therapy can help people cope with the intense emotional difficulties often caused by traumatic early life experiences. New research on why agreeable people might be worse at managing their money. Sandra Matz from Columbia business school explains that it's not because agreeable people are more cooperative negotiators but that they just care less about money. Also in the programme what is emodiversity and can experiencing a range of negative and positive emotions be protective for your mental health? Tim Dalgleish from the MRC Cognition and Brain Sciences unit at the University of Cambridge explains.

Happy Birthday to us! All in the Mind is 30 years old this month and to celebrate we’ve searched the archive to bring you clips of Anthony Clare, the original presenter of the programme, and a very young Claudia Hammond as a reporter. Professor Catherine Loveday is in the studio with Claudia to discuss the pieces of psychology research which have had the biggest impact on them in that time. Last month Donald Trump called for civility after pipe bombs were posted to ten of his most vocal opponents. As America goes to the polls for midterm elections we hear about a new piece of research that suggests civility in politics is not dead. Dr Jeremy Frimer, from the University of Winnipeg in Canada, explains his new research on how approval ratings vary before and after volunteers read tweets by Donald Trump. And what impact does a year in the Arctic have on your mental state? Claudia talks to research psychologist, Dr Anna Temp, who travelled to Svalbard to find out what impact a prolonged stay has on the mental health of scientists working there. How do they cope with the total darkness of the polar nights? And what's it like to be cooped up with 10 of your colleagues and polar bears lurking outside? Producer: Lorna Stewart

55,000 people worldwide completed the BBC Loneliness Experiment. It is the largest survey of loneliness ever done. The results are unique in their scope and reach and were revealed first at an event in the Reading Room of Wellcome Collection. At the live event, presented by Claudia Hammond, musician Jazz Morley and poet Daljit Nagra perform and talk about how their creativity was driven by their loneliness. Philosopher Julian Baggini challenges the idea that loneliness is always a negative experience. And Claudia discusses the results of the Wellcome supported research with Professor Christina Victor of Brunel University and Professor Pam Qualter of Manchester University.
