Can a smartphone application help treat anxiety and depression?


In a joint project between the Universities of Liverpool and Manchester researchers have examined the initial trial of a smartphone application designed to help people manage their problems.

The 'Catch It' app uses some of the key principles of psychological approaches to mental health and well-being, and specifically Cognitive Behavioural Therapy (CBT). Helping users better understand their moods through use of an ongoing diary.

CBT is a therapy that can help you manage your problems by changing the way you think and behave. It is most commonly used to treat anxiety and depression, but can be useful for other mental and physical health problems.

Effective therapies

The widespread use of mobile phones makes effective therapies such as CBT potentially accessible to large numbers of people.

The 'Catch It' app takes users through a process referred to as "Catch it, Check it, Change it". 'Catch it' aims to help the user identify thoughts and thinking styles associated with a shift in mood or a particular emotion.

The study, conducted by researchers from the University of Liverpool's Institute of Psychology, Health and Society (IPHS), the University of Liverpool's Computer Services and the University of Manchester's School of Psychological Science, has been published in the British Journal of Psych Open.

Impacting negative moods

Professor Peter Kinderman, said: "This type of therapy cannot remove problems, but it can help people deal with them in a more positive way. It is based on the concept that your thoughts, feelings, physical sensations and actions are interconnected, and that negative thoughts and feelings can trap you in a vicious cycle.

"Our research examined the uptake and usage rates of this application along with the faithfulness of user responses to CBT principles and their impact on reported negative and positive moods."

A relatively modest proportion of people chose to download the app, once used, the app tended to be used more than once. Also, 84% of the user-generated content was consistent with the basic concepts of CBT.

Beneficial effects

Professor Kinderman, adds: "There were statistically significant reductions in negative mood intensity and increases in positive mood intensity.

"Smartphone apps have potential beneficial effects in mental health through the application of basic CBT principles. More research with randomised controlled trial designs should be conducted."


The full study, entitled 'The feasibility and effectiveness of a novel CBT smartphone app: 'Catch It'', has been published in BJPsych Open today and can be found here once the embargo lifts

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
