Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that are incurred, directly or indirectly, when a variable product owner buys, holds, or redeems interest in an insurance company separate account that invests in the Series II shares of the Fund but does not represent the effect of any fees or other expenses assessed in connection with your variable product, and if it did, expenses would be higher.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 71% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example does not represent the effect of any fees or expenses assessed in connection with your variable product, and if it did, expenses would be higher. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are determined to be below investment grade quality. In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement. The Fund considers debt securities to be below investment grade quality if they are rated BB/Ba or lower by Standard & Poor’s Ratings Services, Moody’s Investors Service, Inc., or any other nationally recognized statistical rating organization (NRSRO), or are determined by the Adviser to be of comparable quality to such rated securities. These types of securities are commonly known as “junk bonds.” The Fund will principally invest in junk bonds rated B or above by an NRSRO or deemed to be of comparable quality by the portfolio managers. The Fund may invest up to 25% of its total assets in foreign securities. The Fund may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. The Fund may also invest up to 15% of its total assets in securities of issuers located in developing markets. The Fund can invest in derivatives, including credit default swap indices and forward foreign currency contracts. The Fund can invest in credit default swap indices which are credit derivatives used to hedge credit risk or take a position on a basket of credit entities. Credit default swap indices allow an investor to gain or reduce exposure on a basket of credit entities in a more efficient manner than transacting in single name credit default swaps. Unlike a credit default swap, a credit default swap index is a standardized credit security and therefore may be more liquid. The Fund can utilize forward foreign currency contracts to mitigate the risk of foreign currency exposure. A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward foreign currency contracts are used to protect against uncertainty in the level of future currency exchange rates or to gain or modify exposure to a particular currency. The Fund can use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated. In selecting securities for the Fund’s portfolio, the portfolio managers focus on junk bonds that they believe have favorable prospects for high current income and the possibility of growth of capital. Before purchasing securities for the Fund, the portfolio managers conduct a bottom-up fundamental analysis of an issuer that involves an evaluation by a team of credit analysts of an issuer’s financial condition. The fundamental analysis is supplemented by (i) an ongoing review of the securities’ relative value compared with other junk bonds, and (ii) a top-down analysis of sector and macro-economic trends. The portfolio managers attempt to control the Fund’s risk by (i) limiting the portfolio’s assets that are invested in any one security, and (ii) diversifying the portfolio’s holdings over a number of different industries. The portfolio managers will consider selling a security if (1) there appears to be deterioration in a security’s risk profile, or (2) they determine that other securities offer better value.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Credit Risk. The issuer of instruments in which the Fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer’s credit rating. Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, leverage, correlation, liquidity, tax, market, interest rate and management risks. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors. Developing/Emerging Markets Securities Risk. Securities issued by foreign companies and governments located in developing/emerging countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries. Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. High Yield Bond (Junk Bond) Risk. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time. Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. Series II shares performance shown prior to the inception date is that of Series I shares adjusted to reflect the Rule 12b-1 fees applicable to Series II shares. Series II shares performance shown for 2002 is the blended return of Series II shares since their inception and restated performance of Series I shares adjusted to reflect the Rule 12b-1 fees applicable to Series II shares. All performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund’s expenses. The performance table compares the Fund’s performance to that of a broad-based securities market benchmark, a style specific benchmark and a peer group benchmark with investment objectives and strategies similar to the Fund. The performance table below does not reflect charges assessed in connection with your variable product; if it did, the performance shown would be lower. The Fund’s past performance is not necessarily an indication of its future performance. Updated performance information is available on the Fund’s Web site at www.invesco.com/us. Series I shares are not offered by this prospectus. The Series I shares and Series II shares invest in the same portfolio of securities and will have substantially similar performance, except to the extent that the expenses borne by each share class differ. Series II shares have higher expenses (and therefore lower performance) resulting from its Rule 12b-1 plan, which provides for a maximum fee equal to an annual rate of 0.25% (expressed as a percentage of average daily net assets of the Fund).

[1] The Adviser has contractually agreed, through at least June 30, 2013, to waive advisory fees and/or reimburse expenses of Series II shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed below) of Series II shares to 1.05% of average daily net assets. In determining the Adviser's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement to exceed the number reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items, including litigation expenses; (v) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Unless the Board of Trustees and Invesco Advisers, Inc. mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2013.

[2] Series II shares' performance shown prior to the inception date is that of Series I shares restated to reflect the 12b-1 fees applicable to the Series II shares. Series I shares' performance reflects any applicable fee waivers or expense reimbursements. The inception date of the Fund's Series I shares is May 1, 1998.
