Understanding and Managing Suspicion: Research, Coping Strategies, and Professional Support

Whether experienced as a symptom of a mental health condition or as an occasional part of everyday life, feelings of suspicion and mistrust can be challenging and distressing. However, with specific coping techniques and appropriate support, it’s possible to address these feelings effectively. To understand how to manage suspicious thoughts, it’s helpful to first explore what these experiences are and which mental health concerns might feature them as symptoms.

What are suspicious thoughts and paranoia?

Suspicious thinking is characterized by mistrust and wariness, often directed toward other people or one’s environment. Individuals experiencing these thoughts may believe that people or organizations intend to harm them, even when little or no evidence supports these assumptions. They might also misinterpret innocent comments or actions as threatening, potentially straining their personal relationships.

While persistent suspicion can be part of specific mental health conditions, research indicates it can also occur in individuals without underlying mental health concerns. In the 2017 scientific article An Evolutionary Perspective On Paranoia, researchers suggest that suspicious thinking should not be viewed solely as a symptom of mental health disorders but also as an element of typical human psychology. However, they also note that as chronic suspicion becomes more severe, it may begin to fit the definition of certain mental health conditions.

When suspicious thinking becomes a mental health concern

If suspicious thoughts persist and become consistent, they may indicate a personality disorder characterized by paranoia. This is a mental health condition that can cause an individual to believe that those around them (even close friends or loved ones) are lying or plotting against them. Those with this condition may become preoccupied with proving their assumptions, searching for evidence, and finding connections, even if these don’t actually exist. If someone does wrong them, individuals with this condition are likely to never forgive that person, even if the transgression was minor or occurred many years ago.

How are persistent suspicious thought patterns diagnosed?

According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), there are several diagnostic criteria for personality disorders characterized by paranoia. These include:

1. “Pervasive suspiciousness and distrust of others in a manner that means their motives are interpreted as malevolent. This distrust begins by early adulthood and is present in a variety of contexts, as indicated by four or more of the following:

  • Believes there are hidden threats or demeaning messages in benign events or remarks
  • Suspects others are harming, exploiting, or deceiving them, without sufficient basis
  • Reluctant to share sensitive information or confide in others due to a belief that information will be used against them
  • Doubts their friends or associates and become preoccupied with others’ loyalty and trust
  • Holds grudges and does not forgive injuries, insults, or slights
  • Believes that others are attacking their reputation or character, even if this is not apparent to others
  • Has recurrent and unjustified suspicions regarding the fidelity of their spouse or partner”

2. Symptoms aren’t caused by another mental health or medical condition.

Other conditions can also involve suspicious thinking to varying degrees. However, these often have different symptoms and treatments, and seeking professional support is recommended for those experiencing signs of these conditions. For individuals who aren’t experiencing these specific conditions, it may be helpful to explore general ways to cope with suspicious thoughts.

How to cope with suspicious thoughts

Coping with suspicion and paranoid thoughts can be challenging, but several methods may be beneficial. According to mental health experts, these methods may include challenging your suspicious thoughts, engaging in mindfulness and relaxation, and getting proper sleep. While a person experiencing signs of a serious condition should also talk to a licensed clinical social worker or other mental health professional, these methods may help reduce symptoms and improve overall well-being.

How to challenge suspicious thoughts

Challenging suspicious thoughts can involve asking yourself questions when these thoughts occur. These questions can help establish a clearer perspective on what is happening and whether you are interpreting events realistically. Examples of questions may include:

  • Is there clear evidence, or am I basing my worries on feelings?
  • Have I discussed my worries with others?
  • Would a loved one or family member agree that my suspicions are realistic?
  • Is there evidence that contradicts what I believe?
  • Is it possible that I’ve misinterpreted the significance of a threat?
  • Is there another way to interpret these events?

It may also be helpful to test your suspicious feelings and thoughts, which may involve stepping outside your comfort zone. For example, if you are afraid—without specific reason or cause—that something bad will happen if you go to the park, it might be beneficial to go there during the day for a few minutes, possibly with a friend. However, this process may be stressful, so finding ways to relieve stress is also important.

How mindfulness and relaxation can help with suspicious thinking

Mindfulness and relaxation techniques can benefit many individuals, including those experiencing suspicious thoughts. One example is keeping a journal, which could allow a person to record their thoughts and various aspects of their suspicion, making it easier to share with mental health professionals. Other mindfulness and relaxation techniques include:

  • Meditation
  • Deep breathing techniques
  • Yoga
  • Tai chi
  • Progressive relaxation
  • Music and art therapy

How to get proper sleep to potentially alleviate suspicious thoughts

In addition to these techniques, ensuring that you are well-rested can help keep stress levels low and combat suspicious thinking—especially since sleep deprivation is a known contributor to these symptoms. Therefore, getting proper sleep is essential.

Getting proper sleep can help regulate emotions and reduce physical symptoms that may contribute to suspicious thoughts. According to Harvard Health Publishing, there are several ways to improve sleep, including avoiding overeating close to bedtime, limiting or avoiding certain substances, exercising regularly, and maintaining proper sleep hygiene.

Avoid overeating close to bedtime and limit certain substances

While being hungry can interfere with sleep, a large meal right before bedtime can cause your body to focus on digestion instead of rest. As such, leaving two to three hours after a big meal before sleep can be beneficial. Avoiding substances like alcohol and caffeine can also be helpful, as these can disrupt sleep during the night.

Exercise regularly

Regular exercise can have various benefits for sleep, including increasing the production of hormones such as melatonin. Exercising in the morning after the sun has risen can also help regulate a person’s circadian rhythms, which can further improve sleep quality. However, it’s important to note that heavy exercise too close to bedtime can be detrimental to sleep.

Maintain good sleep hygiene

Sleep hygiene practices can allow your body to wind down before sleep and associate certain spaces with bedtime. For example, leaving electronic devices and other sources of stimulation outside your bedroom can allow your body to connect your bed with the act of sleep. Improving the sleep environment by ensuring your room is dark and at a comfortable temperature can also be beneficial.

What to do if you are still struggling with suspicious thoughts

While self-care and coping techniques can be beneficial, they may not be enough to overcome persistent suspicious thinking. When these thoughts are a sign of an underlying mental health condition, professional treatment is typically required to address this and other symptoms effectively.

Can mental health treatments help with suspicious thinking?

Whether a given mental health treatment will be effective for suspicious thoughts depends on many factors, from the type of concern and treatment to the level of treatment adherence and any co-occurring conditions the person may have. It’s generally important to consult with a mental health specialist for persistent suspicious thinking. A licensed clinical social worker at ReachLink can provide an assessment, which can help determine which treatment options are likely to help reduce these symptoms.

Mental health treatment options for suspicious thinking

According to mental health experts, there may be several ways to address suspicious thinking depending on the cause and severity. These include:

  • Therapy: Several types of therapy could help individuals experiencing suspicious thinking, such as cognitive behavioral therapy (CBT) or dialectical behavior therapy (DBT). These therapeutic approaches could help someone identify thought patterns contributing to their suspicion and find ways to restructure them. A licensed clinical social worker can also provide a space to discuss other challenges in everyday life, including those that may worsen suspicious thoughts.
  • Specialized Treatment Programs: For individuals with more specific needs, ReachLink offers specialized treatment programs that address various mental health concerns, including those involving suspicious thinking.
  • Referrals for Additional Support: In cases where symptoms are severe or require medication management, ReachLink’s licensed clinical social workers can provide appropriate referrals to qualified medical and mental health professionals in the client’s area who can prescribe medications if needed.

While in-person therapy may be the traditional approach, it’s not always available or convenient for everyone. Some individuals may live in remote areas or locations lacking sufficient mental health services, while others might find it difficult to leave home because of their symptoms, a disability, transportation issues, or other reasons.

Those experiencing suspicious thoughts may also feel uncomfortable visiting a therapist in person, preferring instead to attend sessions from their own home. In these situations, ReachLink’s telehealth services provide a valuable alternative. Research suggests there are often no significant differences between telehealth therapy and in-person therapy across various outcomes, including overall improvement, client satisfaction, and symptom severity after treatment.

Takeaway

Suspicious thinking and related conditions can be difficult to overcome. However, there are ways to cope with these experiences, including challenging suspicious thoughts, engaging in mindfulness and relaxation practices, and getting proper sleep. In many cases, individuals will benefit from professional assistance. Depending on the nature and severity of their condition, this can involve various types of therapy, such as CBT and DBT, provided by ReachLink’s licensed clinical social workers through secure, convenient telehealth sessions.

Through ReachLink’s comprehensive approach to mental health care, individuals experiencing suspicious thoughts can access the support they need to develop healthier thought patterns and improve their overall well-being.
